JSTL Test Boolean Question

[samdoyle]

I'm not sure why it doesn't appear to work or if I am doing something incorrectly.

Here is basically what I have.

<rich:column>
 <c:choose>
 <c:when test="${sop.isRequired}">
 <h:outputText value="#{sop.name}" style="color:#ff0000" />
 </c:when>
 <c:otherwise>
 <h:outputText value="#{sop.name}" />
 </c:otherwise>
 </c:choose>
</rich:column>

With this I never see the style applied and just the standard text output.

If I change:

<c:when test="${sop.isRequired}">
to
<c:when test="${true}">

The style is applied. I know that the values are correct for the isRequired field since when I just ouput the value such as:

<h:outputText value="#{sop.isRequired}" style="color:#ff0000" />

I will see the mix of true and false values rendered.

Thanks, S.D.

Not sure if this is your problem, but have you tried this?

<c:when test="#{sop.isRequired}">

Yep tried that as well to no avail.

c:when is evaluated when the component tree is created (typically right at the beginning of the renderResponse phase). It's used to determine which components get added to the tree. I'm guessing you want the decision to be made later, for each row. So you actually want both components added to the tree, but you only want one or the other rendered for any given row.

So, you probably want something like this:

<rich:column>
 <h:outputText value="#{sop.name}" style="color:#ff0000" rendered="#{sop.isRequired}"/>
 <h:outputText value="#{sop.name}" rendered="#{not sop.isRequired}"/>
</rich:column>

Excellent and thanks, that did the trick.
