[JBoss JIRA] (RF-12654) PartialViewRender skips check for whether column is rendered before checking if children can be rendered

Ken H updated RF-12654:
-----------------------
Description:
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:
{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}
Clicking the Test button would result 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'.

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.
This behavior exists at least as far back as 4.1.0.Final.

<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}
Clicking the Test button would result in a stack trace similar to the following:
