Keyboard Shortcuts in my JSF page - java

I was wondering if there is a way to make an easy keyboard shortcut in my JSF page
each page has several buttons and I would like to be able to have a user press something like alt+a to activate a button called 'Add Report to Group'
in .net you just put an & before the letter you want to be the shortcut key, is there an option like this in JSF (apart from writing some javascript code which is what I found on the web)

Use the HTML-provided accesskey attribute which is also mapped in <h:commandButton> and <h:commandLink>.
<h:commandButton value="Add" accesskey="a" action="#{bean.add}" />
This button can then be invoked by Alt+A or Shift+Alt+A, depending on the browser used.

jsf can I close browser tab from bean?

My application is managing software, and for user convenience, I want to allow them to open multiple tabs for changing parameters of more than one record at a time. But after finishing whatever they doing, the tabs stays open, and I got some complains about that. So basically my question is:
If there's any way to close browser tab that sends a request to method in my backing bean? for example:
JSF page:
<h:commandButton value="Public score"
action="#{assignmentBean.publicSelected()}">
</h:commandButton>
Bean method:
public void publicSelected() {
application.setAssignmentStatus(done);
dataAccess.mergeEntity(application);
}
is there any way to add something after merging command and close browser tab that activated method? Thanks for help
FULL CODE FOR SOLUTION I'm bad with mixing JS and JSF, so for any of you that are also bad at this I post full code solution using Tiago Vieira Dos Santos hint.
Now my button code looks like:
<h:commandButton value="Public score"
action="#{myBean.doThings}">
<f:ajax execute="#this" onevent="pop"/>
</h:commandButton>
plus on bottom of page I added code as follows:
<script type="text/javascript">
function pop(data){
if(data.status == "success"){
window.close();
}
}
</script>
now after method does what has to be done the window closes.
I think you can be use the javascript command Window.close() then you can put it on oncomplete tag or call in you managed bean using the FacesContext.

Using an OutputLink and Javascript
<h:outputLink onclick="window.open('popup.faces', 'popupWindowName', 'dependent=yes, menubar=no, toolbar=no'); return false;" value="#">
<h:outputText value="open popup" />
</h:outputLink>
With this solution we got control over the appearance of the new browser window. And since there is no postback, there is no validation at all. This is the easiest way to open a new browser window when no model update is needed and no action has to be executed.
In order to implement a proper action handling we need to move the decision whether to open a new window to the action listener.
<h:commandLink actionListener="#{bean.openPopupClicked}" value="open popup" />
public void openPopupClicked(ActionEvent event) {
// code to open a new browser window goes here
}

RichFaces: TabPanel and param

Currently, i am dealing with rich:tabPanel in my web application based on JSF 2.0.
I encounter a very strange problem, which is related to my richface component.
Basically, i print some same stuff on each panel (here, it is a schedule table of a show, tab contains the day and content of tab contains the differents hours ).
Consequently, i have something like that:
<rich:tabPanel>
<c:forEach items="#{show}" var="hour" ...>
<rich:tab>
<a4j:commandLink ...>
<a4j:param value="hour.something" assignTo="#{bean.method}" />
</a4j:commandLink>
</ ..... >
When i click on the first commandlink, when my webpage is displayed, it's ok. But when i choose an other tab, and i click on the commandlink, the "bean.method" is not call. I need to click a second time to make the call of the function.
Finally, when i put the tabPanel as "switchtype=server", it works very well (without clicking 2 times).
But that's not the purpose, i want to use the client mode.
I see that on JIRA of richfaces v3, this problem has been solved JIRA JBoss. But there is no more information (except a comment but it's not working).
If anyone can help, it would be great.
Regards,
The problem is you are using nested forms(form within form). This is not recommended in JSF. Even in HTML it is invalid. Remove one form and it will work.

Why does Wicket change the action attribute of a non-Wicket form tag?

In the base template for the pages of my Wicket application, there's a form I don't want Wicket to handle, like this:
<form id="myForm" action="">
<!-- input fields and submit button -->
</form>
I left the action attribute empty to always send it to the current page. On the application's main page, it works, but on other pages, Wicket adds a "../" in the action attribute, which seems to be meant well but is not what I want.
I'm using Wicket 1.4.17. How can I stop or change this behaviour?
The form is meant to enable the user to submit a short message as feedback to the site admin. It appears on every page and the input is collected from the PageParameters in the constructor of my pages' base class. If there is a more Wicket way to do this, I'll appreciate hints, but this should be a) stateless and b) very very simple.
I'd go the Wicket way and write a component for your feedback form which is then inserted into every page. As you have an (abstract) base class for all of your pages, you can simply add it there and it will appear on every page.
In your feedback form component, simply overwrite the onSubmit() method and send the message to the site admin.

Richfaces: Link-like text with ContextMenu

I want to render using Richfaces a context menu on left click on a link-appearing text (blue text, and underline and cursor onmouseover). So, imagine a link which when clicked shows a context menu. Note that I don't care if the text is indeed a link, I just want it to appear as a link. So, even normal text would be fine, I would make it appear as a link using CSS.
I have the following conditions:
The context menu must appear on client side, without making a request.
The context menu must appear using a rich:componentControl (these "links") are inside a datatable, so the same rich:contextMenu must be re-used.
I still have not found a satisfactory solution, as each approach I have tried has caused a problem for me:
If I use h:outputText (that would be ideal), I cannot attach on it a rich:componentControl (I guess because it cannot fire an onclick event).
If I use a4j:commandLink, although I can attach a rich:componentControl, it makes a server request. I tried to add onclick="return false;" to prevent the request, but Richfaces adds the JS generated by the rich:componentControl after whatever is inside the onclick, which causes this code not to be reached at all, and of course the context menu not to appear at all.
Is there any way to do this? Please remember, no request!
You may try
<rich:componentControl disableDefault="true" ...>
According to documentation with this param componentControl should add return false; itself.
But be aware of corresponding bug: RF-5607
In case documentation lies you may use html anchors. This answer shows how to create a link with componentControl and without page refresh:
<h:outputLink value="#" id="link" onclick="return false;">
<h:outputText value="Link text"/>
<rich:componentControl attachTo="link" for="panel" operation="show" event="onclick"/>
</h:outputLink>
The onclick="return false;" prevents the anchor from scrolling the page to the clicked link.

Enter Key Press behave like Submit in JSF

How to make Enter Key Press behave like Submit in JSF. It works with InputBoxes; but not with inputSecret boxes
I haven't seen this issue before. The chance is little that this behaviour is browser specific. Try in different kinds of browsers to exclude the one and other (IE6/7/8, FF, Safari, Chrome, etc). The chance is bigger that this is caused by a (poor) Javascript key event listener which incorrectly suppresses the enter key (for example a JS password validator which checks the entered characters).
If still in vain, just add the following onkeypress to the h:form:
<h:form onkeypress="if (event.keyCode == 13) this.submit();">
You need to take textareas into account however. If you have them, then you need to copy all onkeypress events over the h:inputXXX elements expect of textareas yourself.
If you want to press ENTER key instead of submit in any form, what we have to do here is add defaultcommand attribute in af:form tag and give id of the submit button as value. Sample code snippet for this is
<af:form id="f1" defaultCommand="cb1">
<af:outputText value="User Name" id="usename"/>
<af:inputText value="#{BackingBean.userName}" id="uname" />
<af:outputText value="Password" id="pword"/>
<af:inputText value="#{BackingBean.password}" id="paword" secret="true"/>
<af:commandButton text="Submit" action="#{BackingBean.method}" id="cb1" />
</af:form>
I made it work by placing an additional inputBox and hiding it using javascript. Let me know if you have any other suggestions
Thanks baluC for pointing me in the right direction

tested with jsf 2. put:
<h:commandButton id="hidden" style="visibility: hidden;" action="#{mybean.myaction()}" />
in your form
From ComputerPilot's answer I came to know that it's bug in IE which wouldn't make the parent form to submit if there's only one input element. To overcome this problem I added one more input Box with attribute style="display:none" and it worked fine.
There is an old specification that pops into my mind with this one. If you have a form that contains just one input field, the behaviour of submitting on the enter-key doesn't work in some versions of Internet Explorer. The easiest fix is to make sure you have more than one input field.
Other reasons for this problem include...
Not having an input of type submit
Having an input of type submit, but it isn't visible on the page (hidden or positioned off-page)
This behaviour is very specific to this browser.
