Consume Wsrp Portlet Error

Question

Hi,I am new to webcenter, and my situation is : I develop a very simple bounded task flow(using page fragement) which just shows the employees list and emplee detail info views, nothing special and it works well in the jsf page as region, then I create the portlet with the task flow and register the wsrp producer in the webcenter space (these steps also go well). However when I drop the portlet into the page , the error displays as below. And then I make the jsf page including the task flow as region to the portlet, when it is dragged into the space page , the portlet content reload and refresh again and again .
My JDeveloper version is:11.1.1.4.0_GENERIC_101227.1736.5923
The Webcenter Spaces vm is download from: http://retriever.us.oracle.com/apex/f?p=121:22:1113718446801055::NO:RP:P22_CONTAINER_ID:49699 . The version is : Oracle WebCenter 11g PS3 ,Oracle WLS 11g PS3 .
I really appreciate somebody could give me some help. Thank you so much.
The error information is:

Hi,
How did you create your portlet?
The default way, how to create a portlet from the ADF project in JDev is the right click on the JSPX page or tasklfow you want to portletize and choose the item "Create Portlet Entry ..." from the menu. The Jdev automatically wraps your ADF project with portlet stuff.
