Rerendering input elements without loosing input

[matinh]

Hi all!

I'm using a4j to enable/disable some calendar input field based on the value of a selection box. I do this by using the following code (simplified)

<h:selectOneListbox size="1" value="#{mybean.variant}">
 <f:selectItems value="#{mybean.allVariants}"/>
 <a4j:support event="onchange" action="#{mybean.doSomething()}" reRender="date2disabler,date2" />
</h:selectOneListbox>
...
<rich:calendar id="date2" value="#{mybean.date2}" disabled="#{not mybean.timeRange}"/>
<h:selectBooleanCheckbox id="date2disabler" value="#{mybean.timeRange}" disabled="#{mybean.variant == 'V1'}">
 <a4j:support event="onchange" reRender="date2"/>
</h:selectBooleanCheckbox>

The problem I have is the following: if a user enters some date in the calendar input date2 and afterwards changes the selectOneListbox, date2 is to be rerendered (and eventually disabled). However, the input entered by the user is lost because of this rerendering.

Is there some easy way to not loose the values?

many thanks in advance,
- martin

I don't get it. How could rich:messages save me from loosing user input on AJAX rerendering?

Oops, I forgot to mention one probably very important thing: the two input elements are within two different a4j:region elements.

Any hints?

For the records: I had to put the various components within the same <a4j:region> tag to solve my problem, as only components within the same region as the component triggering the AJAX request are processed on the server side.
