I can't change the data information in my jsp page when I submit the form and call a java function(When the button is pressed).
This is a peace of code used in my .jsp form field:
...
<h:form>
<h:panelGrid columns="3">
<h:outputLabel for="contactName" value="#{msj.contactName}"/>
<h:inputText id="contactName" value="#{CustodiaBean.name}" required="true">
<f:validator validatorId = "TextValidator" />
</h:inputText>
<h:message for="contactName" styleClass="errorMessage" style="color:red"/>
<h:outputLabel for="contactLastName" value="#{msj.contactLastName}"/>
<h:inputText id="contactLastName" value="#{CustodiaBean.last_name}" required="true" >
<f:validator validatorId = "TextValidator" />
</h:inputText>
<h:message for="contactLastName" styleClass="errorMessage" style="color:red"/>
</h:panelGrid>
<div id="button">
<h:commandLink styleClass="hoveringLink3doubleGreen" action="#{CustodiaBean.updateAccount}">
<h:outputText id="save_button" value="#{msj.save_changes}"/>
</h:commandLink>
<h:commandLink styleClass="hoveringLink3double" action="myAccountCustodia">
<h:outputText id="cancel_button" value="#{msj.cancel}"/>
</h:commandLink>
</div>
</h:form>
...
This is the same piece of code used in other pages like login and register user.
The form fields get the current values in "CustodiaBean", but i try to change the value in the form and when I press the button to check the value(call a function in "CustodiaBean"), I always get the previous value (The new form value is not changed in my class "CustodiaBean").
I'm using a tomcat server and eclipse.
Is necesary to force the field to be bloqued and save the changes when the button is pressed??
I don't know why this is happen. Can anyone help me or give me some advice??
Thanks a lot in advance
Does h:inputText etc also has a property name? Try to see what html is generated. It may be possible that your data is not getting submitted properly. Any HTML form directly submit feilds which are non disabled with the name property of each field. IF id is present and not name, it wont be submitted correctly. Try debugging at browser level or via some firefox plugin like tamper data.
Hope it helps

When I want to "delete a plane" from my jsf page, if successful the plane deletes, and I do a redirect to the page and show an alert telling the user the plane was succesfully deleted. However, the values the user entered in the h:inputText are still there, they dont empty.
JSF Page:
<h:form>
<h:panelGrid columns="3" class="table">
<h:outputLabel value="Plane ID" />
<h:inputText value="#{listAirplaneBB.airPlaneId}"/>
<h:commandButton value="Delete"
class="btn btn-primary"
action="#{addAirplaneCtrl.deleteAirplane}" />
</h:panelGrid>
</h:form>
Bean code:
public String deleteAirplane(){
//delete the plane
return private/user?faces-redirect=true;
}
Any ideas on why the fields dont empty after redirect?
Maybe your listAirplaneBB is a #ViewScoped bean (cant tell by your example).
In that case you have to clean any particular fields manually before redirecting as JSF keeps alive that bean while the target page has not changed.
I am trying to show a value from the database in a input text to update it. so when I click on the column the program show a window with all the values but as an inputtext so the user can't update the values.
I am using PrimeFace 4, jsf and mysql as a database
<i>
<h:panelGrid id="display" columns="2" cellpadding="4">
<h:outputText value="ID:" />
<h:outputText value="#{usersBean.selectUser.idUtilisateur}"
style="font-weight:bold" />
<h:outputText value="Nom:" />
<h:inputText value="#{usersBean.selectUser.nomUtilisateur}"
style="font-weight:bold" />
<h:outputText value="Prenom" />
<h:inputText value="#{usersBean.selectUser.prenomUtilisateur}"
style="font-weight:bold" />
<h:outputText value="Indentifiant" />
<h:inputText value="#{usersBean.selectUser.identifiUtilisateur}"
style="font-weight:bold" />
</h:panelGrid>
<i/>
Any input field should be inside a form (h:form will do) to be processed. You could omit this in case you just want to output the data. But in this case it would be more "correct" to use "output" elements for this task.
Since you use PrimeFaces I would highly recommend using p:inputText (http://www.primefaces.org/showcase/ui/inputText.jsf). It has all the attributes of h:inputText but is more compatible with PF processors.
To show any value inside an inputText you just have to initialize it in the provided managed bean. And of course, if you use partial submit approach don't forget to update the element/container you're trying to show values at.
I have two forms, an one button.
<h:form>
<h:outputLabel value="Form Name: *" />
<p:inputText required="true" value="#{currentTemplate.name}" />
</h:form>
and one button in another form.
<h:form id="orderListForm">
<p:commandButton value="Submit"
action="#{orderListBean.callPersist}" style="margin-top:5px"
id="btnCitySubmit" />
</h:form>
I want to save the value from the first form with the second.
I really appreciate your answer!
Do you want to execute all inputs in both forms? Then process="#all" attribute of <p:commandButton> is for you. It will process all inputs within a page.
Alternatively, you can specify ids of components to be processed, like process="#form :another-form", if to-be-updated form has id="another-form" specified.
Richfaces 3.3.3, Jsf 1.2:
I have a a4j:form that uses some simple validation, mainly required="true" to ensure the form does not get submitted without some necessary data.
I also have some complex data to add (optionally) to the form, so I thought the best way to do this is to have a a4j:commandButton that displays a rich:modalPanel where the user can create the complex data set.
The created data is also displayed in a h:selectManyListbox that is reRendered when the modalPanel is closed.
That's the plan, at least. I have the following problems:
reRender works, but only if I prevent validation via immediate="true" - which in turn seems to prevent the selected data from the modalPanel to be present in the backing Bean
if I remove the immediate tag, the data gets updated, but only if there are no validation errors
What is the best way to get this to work the way I want? Is there another, better way?
UPDATE:
The Validation that fails is in some different part of the form, not in the data entered via the modalPanel, which is displayed in the Listbox
CODE:
modalPanel:
<rich:modalPanel id="addTrimming" domElementAttachment="parent" width="150" height="130">
<f:facet name="header">
<h:panelGroup>
<h:outputText value="Define Filter" />
</h:panelGroup>
</f:facet>
<f:facet name="controls">
<h:panelGroup>
<h:graphicImage value="/images/close.gif" styleClass="hidelink" id="hidelinkAddTrimming"/>
<rich:componentControl for="addTrimming" attachTo="hidelinkAddTrimming" operation="hide" event="onclick"/>
</h:panelGroup>
</f:facet>
<h:panelGrid id="trimsettings" columns="3">
<h:outputText value="Target:" style="font-weight:bold"/>
<h:inputText id="target" label="XML Filename" required="true" value="#{xmlCreator.trimTarget}">
</h:inputText>
<h:outputText value=""/>
<h:outputText value="Mode:"/>
<h:selectOneMenu value="#{xmlCreator.trimMode}">
<f:selectItem itemLabel="Quality" itemValue="quality"/>
<f:selectItem itemLabel="after Primer" itemValue="afterPrimer"/>
<f:selectItem itemLabel="fixed" itemValue="fixed"/>
<f:selectItem itemLabel="Median length" itemValue="median"/>
<f:selectItem itemLabel="Motif" itemValue="motif"/>
</h:selectOneMenu>
<h:outputText value=""/>
</h:panelGrid>
<h:panelGroup>
<a4j:commandButton value="OK" action="#{xmlCreator.createTrimming}" onclick="from:submit()">
<a4j:support event="oncomplete" ajaxSingle="true" immediate="true" reRender="trimsPanel"/>
</a4j:commandButton>
</h:panelGroup>
</rich:modalPanel>
relevant form part:
<h:outputText value="Trimming:"/>
<a4j:outputPanel id="trimsPanel">
<h:selectManyListbox id="trims" value="#{xmlCreator.selectedTrimmings}">
<f:selectItems value="#{si:toSelectTrimmingList(xmlCreator.trimmings)}"/>
</h:selectManyListbox>
</a4j:outputPanel>
<a4j:commandButton id="addTrimButton" immediate="true" value=" + Trimming">
<rich:componentControl for="addTrimming" attachTo="addTrimButton" operation="show" event="onclick"/>
</a4j:commandButton>
If you do it in one form than you should separate it into two: one will be your main form and another will be form inside modal panel. Thus you'll be able to submit modal panel independently of main form and your submit button in modal panel will look like this:
<a4j:commandButton value="OK" action="#{xmlCreator.createTrimming}" reRender="trimsPanel"/>
you should use process with immediate to send modalpanel's data to bean when closing panel with a a:commandButton or a:commandLink.
for this, modal panel data has to be valid as expected, so you will get valid new data and add it to h:selectManyListBox 's bean value and reRender h:selectManyListBox.
this should work. if not please post your a:form and modalPanel code full to check.
I'm currently learning about jsf 2.0 from core jsf 2.0 book + glassfish + cdi.
I have a question about the validation feature of JSF.
Let's say i have a very simple login application, which has a very simple layout like :
userid : (input field for userid - using required="true")
password : (input secret for password - using required="true")
loginButton + registerButton(using immediate="true") + checkUserIdAvailabilityButton
Now, let's say the loginButton is pressed, and the userid and password are left empty, validation error would occur on both of the fields, and that's working as what i intended.
And when the registerButton is pressed, it doesnt care whether the userid or password is filled by the user, since it's using immediate="true", thus bypassing validation and the command gets executed at the apply request value phase, and that's still working as what i intended.
And here comes my problem .. When the checkUserIdAvailabilityButton is pressed, i only expect the userid to be filled, and i dont need to care about whether the password field is filled or not, but the password field will throw error saying that it's a required field.
Is there anyway to resolve this kind of problem ? I know this could be a very simple application, but in my working place, i think they design lots of screens like this, like the save button along with refresh button with different required fields but the buttons are in the same page.
Thank you !
Set both the availability button and username field with immediate="true" and put the register button in a separate <h:form>.
E.g.
<h:form>
<h:inputText value="#{bean.username}" required="true" immediate="true" />
<h:inputSecret value="#{bean.password}" required="true" />
<h:commandButton value="Login" action="#{bean.login}" />
<h:commandButton value="Check name availability" action="#{bean.checkNameAvailability}" immediate="true" />
</h:form>
<h:form>
<h:commandButton value="Register" action="#{bean.register}" />
</h:form>
An alternative is to determine in the required attribute which button is been pressed (it's then present as request parameter).
<h:form id="form">
<h:inputText value="#{bean.username}" required="#{not empty param['form:login'] or not empty param['form:check']}" />
<h:inputSecret value="#{bean.password}" required="#{not empty param['form:login']}" />
<h:commandButton id="login" value="Login" action="#{bean.login}" />
<h:commandButton id="check" value="Check name availability" action="#{bean.checkNameAvailability}" />
<h:commandButton value="Register" action="#{bean.register}" />
</h:form>
