noSelectionLabel doesn`t change on reRender

[barbacena]

Hi,

I've got the following facelet:

<s:decorate id="#{name}">
 <c:if test="#{empty noSelectionLabel}">
  <c:set var="noSelectionLabel" value="----" />
 </c:if>
 <c:if test="#{defautSelectItems and items.size eq 1}">
  <c:set var="noSelectionLabel" value="" />
 </c:if>
 <h:selectOneMenu ... >
  <s:selectItems ... noSelectionLabel="#{noSelectionLabel}" />
 </h:selectOneMenu>
</s:decorate>

The expected behavior of this is when #{items} has only one value and #{defautSelectItems} is true, the #{noSelectionItem} shouldn't show. But what happens is that because the 1st render has no items it show the #{noSelectionLabel} as ----, but when I reRender the selectOneMenu with only 1 item, it keeps showing the noSelectionLabel but it shouldn't show it because the #{noSelectionLabel} is empty.

Do I need to add something at s:selectItems to get this behaviour?

Ty.

you first need to understand what c:if really does.
this may help c:foreach-vs-ui:repeat-in-facelets

Hi Martin,

The problem is nt that. I changed my code to:

<s:decorate id="#{name}">
 <c:if test="#{empty noSelectionLabel}">
  <c:set var="noSelectionLabel" value="----" />
 </c:if>
 <c:if test="#{defautSelectItems and items.size eq 1}">
  <c:set var="noSelectionLabel" value="" />
 </c:if>
 Label: #{noSelectionLabel}
 <h:selectOneMenu ... >
  <s:selectItems ... noSelectionLabel="#{noSelectionLabel}" />
 </h:selectOneMenu>
</s:decorate>

End after the reRender, the displey of noSelectionLabel changes to the value I expect but inside the selectOneMenu it doesn't. I think it is a cache problem. Any ideia?

upps - sorry, I was wrong here

yes, c:if should work in this case

Probably this

I thought so (and even point to the João Paulo) but the jira issue is about the hideNoSelectionLabel functionality which is to hide after a option is selected.

Should I raise another issue or add a comment at this pointing this problem?

Is there a work around already?

ps.: We discussed here and we think the problem is the same as the issue points: caching.

I think it is the same issue.
