--------------------------
Summary: PartialViewRender skips check for whether column is
rendered before checking if children can be rendered
Key: RF-12654
URL: https://issues.jboss.org/browse/RF-12654
Project: RichFaces
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: 4.3.0.M2
Environment: JBoss 7.1.1.Final
Reporter: Ken H
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.
For example:
index.html
{code}
<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>
{code}
Results in a stack trace similar to the following:
{code}
/index.xhtml @33,96 rendered="#{foo.propertyDoesNotExist != null}": The class
'org.richfaces.tests.Foo' does not have the property 'propertyDoesNotExist'.
