Hello,

I am unsing JSF 1.2 with the richfaces implementation.

What I am trying to do is to enable a selectOneRadio when a selectBooleanCheckbox is checked.

It works so far. But there is a strange effect:

Consider following situation:

Field selectA shows an error-Message in its rich:message tag.

After checking myCheckbox selectOneRadio selectToReRender is enabled but the error message in all rich-message tags on the page disappear.

Thanks for your Help.

Regards,

Max

<!-- Field which shows error-Message if vlaue was not entered -->
<h:selectOneRadio id="selectA"
   value ="#{controller.entity.valueA}"
   required="true"
   label="#{text['selectA.label']}"
   layout="pageDirection">
   <f:selectItem itemValue="#{true}" itemLabel="Yes" />
   <f:selectItem itemValue="#{false}" itemLabel="No"/>
</h:selectOneRadio>

<rich:message for="selectA"/>



<!-- Field which enables selectOneRadio selectToReRender if it is checked -->
<h:selectBooleanCheckbox id="myCheckbox"
   label="#{text['myCheckbox.label']}"
   value="#{controller.entity.valueB}"
   required="false">
   <a4j:support event="onclick" ajaxSingle="true" reRender="selectToReRender"/>
</h:selectBooleanCheckbox>
<rich:message for="myCheckbox"/>

<!-- Field which is disabled until myCheckbox is checked.
  Function getSelectToReRenderDisabled() of controller checks the boolean value of controller.entity.valueB -->
<h:selectOneRadio id="selectToReRender"
   value="#{controller.entity.valueC}"
   label="#{text['selectToReRender.label']}"
   layout="pageDirection"
   required="true"
   disabled="#{controller.selectToReRenderDisabled}">
   <f:selectItems value="#{MySelectItems.myEntitySelectItems}"
   var="" />
</h:selectOneRadio>
<rich:message for="selectToReRender"/>
