ajaxSingle=

[christian_koelle]

I work a lot with conditional rendering, i.e

<h:ouputText rendered="#{!condition}" .../>
<h:inputText rendered="#{condition} .../>

I.e. depending on the condition either this or that is intended to be rendered.

I noticed that data input in <h:inputText is not written back into the backing bean properly, if I use <a4j:support> on a widget, which inverts the condition, although ajaxSingle=false.

<a4j:support
 event="onchange"
 ajaxSingle="false"
 reRender="formId ..." />

If I use the following construct, the input data is submitted properly.

styleClass="#{(condition) ? ' ' : 'invisible'}">

Now my question: Is the later workaround the proper practice if I want to show either this or that component?

Regards and thanks in advance.

rendered condition should be stored between request - to be session or conversation scoped. I think you used request.

You can try to use the condition at view-creation-time with

xmlns:c="http://java.sun.com/jstl/core"

<c:if test="#{condition}">
 <h:inputText>
 <a4j:support
 event="onchange"
 ajaxSingle="false"
 reRender="formId ..." />
 </h:inputText>
</c:if>
