I should probably clarify by saying, it shows the link but just will not fire the action when click on it. Another word, the rendered test is successful on panelgrid (hence the link is shown), but the test failed when clicked on the link. Scratch my head on this for two days. Learn a new tricks-of-the-trade, priceless...

I don't understand it but it works. Shasi, I think you are right about the problem is caused by rendered attribute being evaluated as false when clicked. Below is what I did to get it to work. Hopefully you or someone can explain why. The code change that I made to get it to work is on this line only: <h:panelGrid rendered="#{not empty sessionScope.MyAccountLoginType and sessionScope.MyAccountLoginType==resources.LOGIN_TYPE_MY_ACCOUNT }"> It works if I change it to this: <h:panelGrid rendered="#{ sessionScope.MyAccountLoginType=='MA'}"> Note : value of MA is what I have in my message bundle "resources.LOGIN_TYPE_MY_ACCOUNT". Just to be sure, I did <h:outputText value="#{resources.LOGIN_TYPE_MY_ACCOUNT} "/> and it output value of MA correctly. Not sure why I can't use it to perform the rendered test. I tried below and non of them work. But I don't know why: <h:panelGrid rendered="#{not empty sessionScope.MyAccountLoginType and sessionScope.MyAccountLoginType==resources.LOGIN_TYPE_MY_ACCOUNT }"> <h:panelGrid rendered="#{not empty sessionScope.MyAccountLoginType and sessionScope.MyAccountLoginType=='MA' }"> <h:panelGrid rendered="${not empty sessionScope.MyAccountLoginType and sessionScope.MyAccountLoginType=='MA' }"> -----Original Message----- From: Lim Hock-Chai [mailto:[email protected]] Sent: Wednesday, May 09, 2012 1:52 PM To: MyFaces Discussion Subject: RE: commandlink not working in panelgrid I added an onclick="alert(#{not empty sessionScope.MyAccountLoginType and sessionScope.MyAccountLoginType==resources.LOGIN_TYPE_MY_ACCOUNT })" on the commandlink element and the alert showing value of true when I click on the link. <h:panelGrid rendered="#{not empty sessionScope.MyAccountLoginType and sessionScope.MyAccountLoginType==resources.LOGIN_TYPE_MY_ACCOUNT }"> <h:outputText value=" "/> <h:outputText value="|"/> <h:commandLink immediate="true" onclick="alert(#{not empty sessionScope.MyAccountLoginType and sessionScope.MyAccountLoginType==resources.LOGIN_TYPE_MY_ACCOUNT })" style="CURSOR: pointer" action="#{commonTaskBean.fromMSAMBackToMyAccount}"> <h:outputText value="My Account"/> </h:commandLink> <h:outputText value="|"/> </h:panelGrid> -----Original Message----- From: Shasi Mitra [mailto:[email protected]] Sent: Wednesday, May 09, 2012 1:36 PM To: MyFaces Discussion Subject: Re: commandlink not working in panelgrid After u click the link also the expression in the rendered attribute is evaluated. That time it should be returning Faldo and hence ur action isn't being fired. If u remove all the rendered attributes or keep ur bean in session scope, it should work. Try printing the expression u gave in the rendered attribute and check.
