Hello,

I have problem with forEach tag in my dialog page.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <f:verbatim>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <c:forEach items="${DialogManager.bean.metrics}" var="abc">
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1!${abc.fileName}!1
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </c:forEach>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </f:verbatim>
‍‍‍‍‍‍‍

Works properly, but when I try to use forEach in that way:

   
<f:verbatim>
&nbsp;&nbsp;&nbsp; <c:forEach items="${DialogManager.bean.metrics}" var="abc">
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <h:panelGrid columns="1" cellpadding="2" style="padding-top: 4px; padding-bottom: 4px;" width="100%" rowClasses="wizardSectionHeading">
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <h:outputText value="#{msg.project_metrics} #{abc.fileName}!" />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </h:panelGrid>
&nbsp;&nbsp;&nbsp;&nbsp; </c:forEach>
</f:verbatim>
‍‍‍‍‍‍‍‍‍

it doesn't work! abc.fileNme is empty - even though getMetrics is invoked in managed bean.I tried in this way:              <hutputText value="#{msg.project_metrics} " /> ${abc.fileName}!

What I am doing wrong? Can't get it to wrok inside panelGrid .

Thanks for help,
Adam

I need to ask a naive question:

In the first example, you use ${abc.fileName} and the second example you use #{abc.fileName}. What reason do you have to use the different notation? $ versus #
