Document List in task default inbox view

I am invoking an IS service in my model, the ouput of which is document list. I need to show the document list in inbox default view so that every item in a list is a task (One row for each item with task Id). I drag and dropped the document list from Managed beans → task search provider → Business Data → my document to default view. It creates a table but when I go to MWS under my task inbox, nothing shown up there.
