There seems to be a problem in the display of the drop Down Menu when in its menuItem we use the disabled attribute with an EL expression of the following two cases:
<rich:dropDownMenu
1. <rich:menuItem disabled="#{folder.type != 1}" ( not equal -> =)
or
2. <rich:menuItem disabled="#{folder.isLibrary}" ( Boolean )
If we use the equality there is no problem:
<rich:menuItem disabled="#{folder.type == 1}"
This problem seems to be introduced in release 3.3.2.SR1, as in the previous one that functionality worked fine.
fixed in 3.3.3
