I have a process which does not have a Task Manager Endpoint. I use the Email Endpoint. But when a person logs in to Workspace, he can see his tasks for that process and can also complete with the button which i dont't want him to. What should i do to avoid this? Thanks..
You need to customize your workspace and to do this I recommend to follow this document (Customizing the LiveCycle Workspace ES User Interface) "http://help.adobe.com/en_US/livecycle/8.2/customizeworkspaceui.pdf. Under wsSource\adobe-workspace-src\Workspace\src\lc" you should find all the .mxml and .as files. I think you need to check the task directory and especially the ToDo.mxml file.
It is quiet easy to do this modification if you setup your environment for the Flex Builder properly. You should not go wrong if you follow the document that I noted above carefully.
