The 'rendered' attribute accepts any EL expression with a boolean outcome.
Some basic examples:
<h:someComponent rendered="#{myBean.booleanValue}" />
<h:someComponent rendered="#{myBean.intValue > 10}" />
<h:someComponent rendered="#{myBean.objectValue == null}" />
<h:someComponent rendered="#{myBean.stringValue != 'someValue'}" />
<h:someComponent rendered="#{!empty myBean.collectionValue}" />
<h:someComponent rendered="#{!myBean.booleanValue && myBean.intValue != 0}" />
<h:someComponent rendered="#{myBean.stringValue == 'oneValue' || myBean.stringValue == 'anotherValue'}" />
I however recommend you to use a dynamically sizeable h:dataTable or a static h:panelGrid instead of a plain HTML table.
Hi Balu,
Thanks for your reply, i could solve my problem. but when i am using panelGrid to display columns, if one column is hidden...then i am missing the table layout...
<h:panelGrid columns="2">
<h:graphicImage value="/images/a.gif" rendered="#{focal.emp_access.keepAdmin =='Y' }" />
<h:graphicImage value="/images/b.gif" rendered="#{focal.emp_access.optionsAdmin =='Y' }" />
<h:commandLink id="appkeep" action="#{focal.showkeep}" value="Continue" rendered="#{focal.emp_access.keepAdmin =='Y'}"/>
<h:commandLink id="appoptions" action="#{focal.showoptions}" value="Continue" rendered="#{focal.emp_access.optionsAdmin =='Y'}"/>
</h:panelGrid>
in the above code if the second image is hidden , then i am getting the link in the first row. is there any way to control this behavior... ?
