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 (see dataTableBug3.jsf).

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