[richfaces-issues] [JBoss JIRA] (RF-12807) Datatable evaluate value attribute even if rendered=false when doing ajax calls

[Kenny Moens (JIRA)]

     [ https://issues.jboss.org/browse/RF-12807?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Kenny Moens updated RF-12807:
-----------------------------

    Attachment: dataTableBug2.jsf
                dataTableBug3.jsf


Brian Leathem: I've tried with setting the rendered condition on the dataTable itself. It does not change the results and gives the same issue.

I tried this with the attached file (dataTableBug2.jsf).

Additionally if we make use of the c:if tag it works properly. While this is an acceptable workaround, still the rendered property should not allow any of the child components to be considered for execution at all.

Note: it should be easily to reproduce based on the attached files.
