Hi,
Replacing "Failure" with "null" did not work. However, when I added few println statements, I came to know that, reRender is getting executed before, catch block is entered. Hennce, I am getting the value of the of hidden variable as empty.

06/10/20 11:10:24 In get Profile err msg :

06/10/20 11:10:49 In the set profile error message.
06/10/20 11:10:49 In the set profile error message.
(Don't know why two times set profile error message is executed)
(Now the catch block is executed.)

06/10/20 11:10:49 Exception occured.
06/10/20 11:10:49 Error message is set
Is this the right behaviour or reRender? Not sure what I am doing wrong here.
