I want to establish security to level of button in the standard portlets of MWS.
For example, an user enters to the portlet “Business Processes” because he is an administrator but since he doesn’t have a certain role, the button “Delete” appears <disabled>. Hereby he can consult processes but updates are not allowed him.
I’m not clear on exactly what you are asking about.
Are you saying you want to control this behavior in a portlet you are developing? Or you want to change the behavior of a portlet provided by someone else?
