When using rendered on a component within a rich:column of a rich:dataTable, the EL on the component is executed even if the column is not rendered.
The expected behavior (per my loose understanding of the JSF spec) would suggest that the traversal should have short-circuited before checking the unrendered column's children.
This behavior exists at least as far back as 4.1.0.Final.
Given this minimal example:
<rich:dataTable value="#{bean.foos}" var="foo">
|
<rich:column rendered="false">
|
<h:outputText value="#{foo.bar}" rendered="#{foo.propertyDoesNotExist != null}" />
|
</rich:column>
|
|
|
<rich:column>
|
<a4j:commandButton value="Test" action="#{bean.noop}"
|
execute="@this" render="@form" />
|
</rich:column>
|
</rich:dataTable>
|
Clicking the Test button would result in a stack trace similar to the following:
/index.xhtml @33,96 rendered="#{foo.propertyDoesNotExist != null}": The class 'org.richfaces.tests.Foo' does not have the property 'propertyDoesNotExist'.
