Re: commandlink not working in panelgrid
This is one of the basic concepts that you learn as you work with JSF
-- for a UICommand component to perform its action, it must be
rendered on the initial view, and it must also be rendered on the view
created to process the submit.
So whatever condition you use for rendered must involve objects that
exist longer than request scope.
Also, static class variables are not available for use in the EL
expression. I believe non-public class instance variables are also
not available, but I think public ones are. To be on the safe side,
you should provide a bean getter for any variable you want to access
from the EL expression.
So for resources.LOGIN_TYPE_MY_ACCOUNT to work, you would need to
provide a getLOGIN_TYPE_MY_ACCOUNT() { return LOGIN_TYPE_MY_ACCOUNT; }
method on your resources bean.

Subject: RE: commandlink not working in panelgrid
Finally got it to work inside panelgrid. 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

After u click the link also the expression in the rendered attribute is

Are u sure ur bean is in session scope? Befor the action event is fired, it's

Maybe it would be better if rendered attribute evaluation would be skipped

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' }

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

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.

I tried both session and request scopes. Both failed to work. The thing is
that the commandlink is showing on the page, which would mean that the
rendered condition in the panelGroup or panelgrid is ok. It just that when I
click on the link that is inside the panelgroup/panelgrid, it does not work.
I even tried not using any rendered condition on the panelGroup/panelGrid,
the link still not working. Oddest thing.

Are u sure ur bean is in session scope? Befor the action event is fired, it's
verified whether the grid is rendered or not. So if the bean is in request
scope, it returns False and therefore the link's action isn't fired.

I'm currently using myfaces 1.1.9 for my web app. I'm having some problems
with commandlink not working correctly for me. It appears that when
commandlink is inside of the panelgrid, it is not calling the method
specified
