primefaces commandbutton update does not work [duplicate]

Answer 1

Are you sure that test() method is invoked? If yes, can you try with following update expression?

update="@([id$=wbTestPanel])"

Otherwise, it maybe the case that test() method is not called because of a validation error. If that is the case, you can inspect it with debug or firebug.

Answer 2

Use : before id
