Shadow Creeper updated RF-4458:
-------------------------------

    Description: 
If disabled was true, the expected behavior (not allowed to click on disabled element) is seen.

If disabled was false, the EL will be rechecked after click but before actionListener is run.

Expected behavior:
If disabled was false, then the button should work without checking disabled EL unless and until the button is told to reRender.
