Yes, I do have two different beans, but the code inside the 'rendered' block is getting evaluated even when the condition is false.
To dynamically change the component tree based on internal structures, it appears that constructs like <ui:repeat> / "rendered" / <c:forEach> are not working too well. I am having better success by binding a h:panelGroup to my Java code, and from Java code, programmatically manipulate the tree. However, it is not as convenient as scripting. -- venkat -----Original Message----- From: Mr Arvind Pandey [mailto:[EMAIL PROTECTED] Sent: Wednesday, August 02, 2006 11:02 AM To: MyFaces Discussion Subject: RE: "rendered" condition does not work as expected Hi Venkat! If you have two pulic classes then there must be two different beans in your xml file, say circle and rectangle. In first panelGroup use rendered="#{circle.objType == 'circle'}" and in second one use rendered="#{rectangle.objType == 'rectangle'}". It seems as if in your code rendered property is working as expected.
