I have the following issue:
I have a home page where I load the URL with the following structure:
public class HomePage extends BasePage {
public HomePage(WebDriver driver) {
super(driver);
getDriver().get("URL");
}
Then I have another page, which extends from the HomePage:
public class OptionsPage extends HomePage {
public OptionsPage(WebDriver driver) {
super(driver);
}
Now, the issue is on the test, where I want to get the OptionsPage from an action (let's say clicking a button present on HomePage). It seems that the page just loads again once I call it:
// Open page
HomePage home = getHomePage(); //loads URL from BasePage
// click on some option which takes me to the OptionsPage
OptionsPage options = home.clickOnRandomOption(); //this method right here loads the URL again, from there the assertion fails since the page just loads again.
Assert.assertTrue(options.isRandomOptionSelected(), "Obviously it wasn't selected.");
The method to click the option on the home page looks like this:
public OptionsPage clickOnRandomOption() {
getWait().until(ExpectedConditions.elementToBeClickable(RandomOption));
RandomOption.click();
return new FlightOptionsPage(getDriver());
}
Can anyone help me out?
Your challenge is that when you instantiate your optionsPage you're executing all constructors up the chain.
From your code structure, you're running: OptionsPage -> HomePage -> BasePage every time you want to create an optionsPage. It's the testing POM equivalent of the Gorilla-banana-jungle problem.
I can see that the return type from home.clickOnRandomOption() is an OptionsPage so I'm assuming that's where you instantiate the options page.
Two suggestions - either of them will fix your problem, but I recommend you think about implementing both:
Don't chain your pages like that. Keep each one separate and ONLY extend once i.e. each page only extends from BasePage. If there is a common method which more than one page needs, put it in your BasePage and there's no need to extend page from other pages.
Don't execute test-context-impacting code in your constructors - use contructors only for initating variables. By this, I mean that when you create your HomePage do not navigate (driver.get("URL")) in the constructor. This will cause future complications for you when you run tests. For example, what if, you wanted to start on pageX and navigate to home via an auto-redirect then do more actions on home? - your POM won't support it as when you create homePage you're going to navigate the URL to there.
The ZK setLabel() function of Button widget does not work; when the code runs to the line like foobutton.setLabel(mystring), the button disappears from the browser.
In the eclipse IDE, if I hover on the setLabel() function, the IDE shows this message:
If label is changed, the whole component is invalidate.Thus, you want to smart-update, you have to override this method.
Using ZK 8.5.0
Inside the controller class, I declare:
#Wire
Button delSelectedMonitor;
Inside the controller, I implement a class which implements EventListener:
public class onClickHolderEditMode implements EventListener{
public void onEvent(Event event) throws Exception {
clickedDivEditMode = (Div) event.getTarget();
clickedDivIdEditMode = clickedDivEditMode.getId().split(myUtil.monitorholderString)[1];
String curName = getCamNameById(clickedDivIdEditMode);
delSelectedMonitor.setLabel("DELETE:"+clickedDivIdEditMode+","+curName);
}
}
event binding:
tmpdiv.addEventListener("onClick", new onClickHolderEditMode());
My expectation is that when someone clicks the tmpdiv, the button delSelectedMonitor will change its label according to the property of tmpdiv. However as I say previously, the button is just disappearing.

I have tried the section "Specify Your Own Widget Class" at the above website link, but the browser will be pending.
Please help, thank you.
I would prefer a different approach.
Why not use a
<button label="#load(vm.xyz)" ... />
(I wrote using MVVM pattern) and modify variable xyz in clicking action?

I have implemented a simple GWT app that uses 1 Place and 1 Activity (which I have implemented as a Presenter which extends an AbstractActivity and which contains a Composite "view" subclass). The 1 and only UI object in the view is a GWT-Bootstrap NavBar that I want presented at the very top of my "home page".
I'm running the app locally from inside Eclipse and am not getting any compiler or runtime errors. When I go to the URL that the Development Mode console points me to, I get a slight pause in the browser (I assume this is the browser "downloading" the JavaScript) and then I see a blank white screen (instead of my NavBar). The window title is correct (I set this in the module's HTML page) and when I view source I see the same HTML source, so I know that the app's JavaScript is getting to the browser properly. It's just not rendering the NavBar.
I have sprinkled System.out.println() statements throughout onModuleLoad(), my default ActivityManager, ActivityMapper, PlaceHistoryMapper, presenter and view Composite, and all these sysout statements print in the dev console; telling me that I have wired everything together correctly, and that at runtime when the PlaceHistoryHandler#handleCurrentHistory method is called (from inside onModuleLoad), I should be seeing my NavBar.
The only possibilities I can think of are:
I have configured gwt-bootstrap incorrectly; or
I'm not using UiBinder correctly
Something else is wrong with how I am using Activities and Places, or perhaps how I am attaching the UI to RootLayoutPanel inside onModuleLoad().
As for gwt-bootstrap:
I placed the JAR on my project's classpath (I know this because when I include a new UiField of type NavBar inside my widget/view, I don't get any compiler errors)
I added <inherits name="com.github.gwtbootstrap.Bootstrap"/> to my GWT module XML
So if there's anything else I have to configure, please let me know!
As for the UiBinder stuff, here's my widget/view:
public class WebRootDisplay extends BaseDisplay {
private static WebRootDisplayUiBinder uiBinder = GWT
.create(WebRootDisplayUiBinder.class);
interface WebRootDisplayUiBinder extends UiBinder<Widget, WebRootDisplay> {
}
#UiField
Navbar navBar;
public WebRootDisplay(EventBus eventBus) {
super(eventBus);
System.out.println("I get this printing to the console at runtime.");
initWidget(uiBinder.createAndBindUi(this));
System.out.println("...and this too!");
}
}
<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent">
<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder"
xmlns:g="urn:import:com.google.gwt.user.client.ui"
xmlns:b="urn:import:com.github.gwtbootstrap.client.ui">
<g:HTMLPanel>
<b:Navbar ui:field="navBar">
<b:Nav>
<b:NavLink href="http://www.google.com">
Home
</b:NavLink>
</b:Nav>
</b:Navbar>
</g:HTMLPanel>
</ui:UiBinder>
One thing I noticed is that I've got my NavBar inside an HTMLPanel in the UiBinder XML. I did this because I used the Google-Eclipse plugin to generate a new UiBinder for me (which autogenerated both the Composite (which I then modified to extend BaseDisplay, which itself extends Composite) as well as the UiBinder snippet. I figured GWT wants me to put all the UI fields inside this HTMLPanel...(?)
If I'm missing anything here please let me know. I'm not instantiating the NavBar field because I believe that's what createAndBindUi does for me.
If both my gwt-bootstrap config and my use of UiBinder looks correct, then something else is obviously wrong and I will have to post more code. I just wanted to hold off on that initially before these first two items were ruled out. Thanks in advance!
Update
Here is onModuleLoad:
public void onModuleLoad() {
// Some homegrown DI stuff. I have verified that the injector works properly.
ApplicationScope appScope = new ApplicationScope();
setInjector(new ApplicationInjector(appScope,
InjectorProvider.newMasterProvider()));
// Add the sole composite child to the RootLayoutPanel.
// I have verified that injectWebRootDisplay returns a fully configured
// WebRootDisplay instance.
RootLayoutPanel.get().add(injector.injectWebRootDisplay());
historyHandler.register(placeController, eventBus, defaultPlace);
historyHandler.handleCurrentHistory();
}
Could you paste the onModuleLoad() part of your code please?
If you don't got any Exception and error message, I think you should check that you add the view properly to the RootPanel, or when you run the app you should check that the view is there in a div in the HTML and just unvisible or something similar.
The UiBinder part looks fine in a first look.
EDIT:
This onModuleLoad() doesn't said too much to me, but you could try something.
I always use the RootLayoutPanel.get() method in the following way:
RootLayoutPanel.get("someDivId").add(injector.injectWebRootDisplay());
So I always add a div or table to the placeholder HTML with a id, so you can refer to that div when you get the RootPanel. I'm not confident about this is necessary, but I saw this at the first time, and it's working properly.
If you have question or problem, please let me know. :)
Well, I've tried a local example looking exactly like yours code, and I think that problem is not in UI binder. The code you provided so far, is correct, so it most likely that the error is somewhere else.
The biggest suspect is the BaseDisplay class. As far as I can see, this class is not from GWT or gwt-bootstrap. You can really quickly check it, by changing WebRootDisplay class, so it extends classic GWT Composite class instead of BaseDisplay (and disabling all mvp stuff for while). If it works, you have a proof that the problem is caused by 'BaseDisplay'
Since I don't have the full code, I can only assume that WebRootDisplay is used also for displaying the views, and most likely the error is that when view is added to that class, previously added widget (in your case it is a NavBar which you add in constructor of WebRootDisplay) is removed. Most likely the problem should be in methods setWidget and initWidget
In my experience with GWT Activities and Places, a common culprit of a blank white page is failing to register the Place's Tokenizer with the PlaceHistoryMapper as so:
/**
* PlaceHistoryMapper interface is used to attach all places which the
* PlaceHistoryHandler should be aware of. This is done via the #WithTokenizers
* annotation or by extending PlaceHistoryMapperWithFactory and creating a
* separate TokenizerFactory.
*/
#WithTokenizers({
MyPlace.Tokenizer.class,
SomeOtherPlace.Tokenizer.class})
public interface AppPlaceHistoryMapper extends PlaceHistoryMapper {}
See https://developers.google.com/web-toolkit/doc/latest/DevGuideMvpActivitiesAndPlaces#PlaceHistoryMapper
Another cause for a white page (particularly when using RootLayoutPanel.get() with a single place is failing to map the place correctly in the ActivityMapper:
/**
* AppActivityMapper associates each Place with its corresponding
* {#link Activity}
*
* #param clientFactory
* Factory to be passed to activities
*/
public class AppActivityMapper implements ActivityMapper {
private ClientFactory clientFactory;
public AppActivityMapper(ClientFactory clientFactory) {
super();
this.clientFactory = clientFactory;
}
#Override
public Activity getActivity(Place place) {
if (place instanceof MyPlace)
return new MyActivity((MyPlace) place, clientFactory);
else if (place instanceof SomeOtherPlace)
return new SomeOtherActivity((SomeOtherPlace) place, clientFactory);
return null; // If your return null with single place bound to RootLayoutPanel
// you may get a blank white page
}
}
See https://developers.google.com/web-toolkit/doc/latest/DevGuideMvpActivitiesAndPlaces#ActivityMapper
Without a more complete code sample it is impossible to determine exactly what is happening, but the two causes outlined above are common oversights which may help anyone who comes across this thread.
Instead of System.println use GWT.log messages. Then open the Javascript console (of Firebug or Chrome) and see where your code ends up. GWT.log will print out in the browser console, so you can see what the compiled JS code does.
Also, if you compile with the Pretty mode, you'll see the generated Javascript code in the browser and be able to step through and see what is being called (or not).
I am developing a Java ME program. The different forms are located in separate classes. I tried to switch display between main MIDlet and a class and succeeded. How to do the same between two classes? I am just a beginner in Java ME.
I use following code for the same,
First display a static Display variable in Midlet
private static Display display;
Now initialize the dislplay variable in class Constructor
public MyMidlet() {
display = Display.getDisplay(this);
}
Now declare a getDisplay() method in Midlet class
public static Display getDisplay () {
return display;
}
Now you can use this getDisplay() method to get the current Display's object and then set any class's form
MyMidlet.getDisplay().setCurrent(form);
Simplification is:
Display.getDisplay(this).setCurrent(screen);
Where screen is an instance of LCDUI (Form, Alert...) or intance of Canvas object.
The this is an instance of the MIDlet
I have created an application using the texttospeech api and I have all the functionality within one class. I would like to split this into several classes but when I do so I have a null exception error.
The texttospeech api has onclick buttons. Within these buttons I try to call a method from another class for the functionality.
I extend the class 1 with the current class I am using.
I then add the method image() within the class 1:
public void image() {
if(currentHelloIndex==0){
alertDialog.show();
}
else if (currentHelloIndex == 2) {
Image.setImageResource(R.drawable.books);
} else if (currentHelloIndex == 3) {
Image.setImageResource(R.drawable.mic);
}
Currently no variables are declared in class 1 as it is using the variables in the main class.
I then call this method in the main class. This doesn't seem to be working the class 1 has no onCreate method it is just a standard class which extends the main class.
I would appreciate any help on this as I need to separate the functionality into separate classes.
Edit:
currentHelloIndex is an int which is set to 0 in the main class
if the button is clicked an currentHelloIndex is 0 an alertdialog in the main class will appear
if the button is clicked and currentHelloIndex is 2 this will set the Image which is an ImageView in the main class with the image set.
I have put into the main class: static SoundGameScore sound;
Within the main class I have called sound.Image(); in an onclick. Please can someone let me know what I have done wrong, thanks.
You should use some of the refactoring functionality in your Java IDE (you ARE using a Java IDE, right?)
