Dynamic component hiding question

[progzmaster]

Hi i am trying to do something that follows:

There should be one selectOneMenu and two inputText fields
If you select one option from selectOneMenu only one from above inputTexts should be visible/rendered. If you choose another option, another component should be visible. but other should be hidden. How to achieve this.

I've done a form with those components and bind them to jsf bean properties, but when i try to setRendered( false ) on inputText with a4j:support reRender with id of this inputText it don't get hidden.

Where is my mistake ?
Please help me

Can you post your code snippet here?

I think you should try putting inputText inside panel and reRender that panel.

[progzmaster]

i declare inputText components in my jsf bean

private HtmlInputText companyInput;
private HtmlInputText personInput;

.. and initialize it
companyInput = new HtmlInputText();
companyInput.setValue( "" );
companyInput.setRendered( false );

personInput = new HtmlInputText();
personInput.setValue( "" );
personInput.setRendered( false );

.. then bind in jsf page
<h:inputText id="companyInput" binding="#{training.companyInput}" >
<h:inputText id="personInput" binding="#{training.personInput}" >

.. of course bean training is declared if faces-config

<managed-bean>
<managed-bean-class>beans.TrainingBean</managed-bean-class>
<managed-bean-name>training</managed-bean-name>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>

.. and richfaces elements on selectOneMenu...

<h:selectOneMenu id="trainingType" value="#{training.trainingType}" >
<a4j:support event="onchange" reRender="companyInput,personInput" actionListener="#{training.updateView}" immediate="true" />
<f:selectItem itemValue="one" itemLabel="Option one />
<f:selectItem itemValue="two" itemLabel="Option two" />
</h:selectOneMenu>

and in updateView() i would like to do something like

getCompanyInput().setRendered( true );

so after reRendering of companyInput the component wil be visible

Ok i have figured out the problem.
When HtmlSelectOneMenu have immediate attribute set to true everything is ok because i have no validation on form components.

When I add some validation for example required="true"
everything breaks because a4j:support actionListener
is not called before process validation phase.

If I add immediate="true" to a4j:support
then actionListener is called but I don't get
valid value of selectOneMenu.

What should I do ?

you should wrap to a4j:region the component that should be processed without another components validation. immediate is unnesessary in this case.
