rendered problem jbpm
Hi,
I have a problem with the rendered.
I have a creaDoc.xhtml where the user chooses a template using a combox. The template contains the information on which kind of process should begin.
documentoHome.java checks the value and return a true or false value through a method.
documentoList.xhtml is the page that manages the process choosen by the user. It checks the value given back by the method and then displays or hiddens the buttons of the process using the rendered.
The problem comes up when I try to click on the displayed button (or buttons): an error comes up.
Is there something that I'm missing about the use of the rendered (since, if I don't use it, everything works)?
