The Icon is set at the process level.
This means that if you have several workspace startpoints in the same process, they would all have the same icon.
Thanks for your reply. My organization has one major workflow which has more 25 workspace startpoints in it. It is really annoying the users to locate particular form as they all have the same Icon.
I working on the workspace source code to display different icons for each process card in the same workflow. Somewhat moving in the right direction I believe
I succeeded in my Idea. Just modified the workspace flex source and got multiple images for each process card in the same process.
