conditionally required variables is indeed somewhere on the list (afaik). If the required, write, read attribute is changed into something like required='true' or some EL expression with the transitionname in the expression, that could be realized. Achieving this now is possible by making the variable not required in the pd, but checking some things with dhtml in the client. Another option is to implement your own taskcontroller and achieve it that way. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3958912#...
