PAGE_NOT_FOUND in GP UWL

Question

Hi all,
I encountered PAGE_NOT_FOUND error in the GP RUNTIME as well as the GP UWL when the user click on the his task listed in the "Processes which I Own".
This user has its role assigned to the owner in the GP.
Do you guys know what is wrong and how to resolve?
I am currently using CE7.1 and my uwl configuration xml is as followed:
<?xml version="1.0" encoding="UTF-8"?>

I had this problem too. This is what I did:
Check this lines in your xml:
<Property name="page" value="pcd:portal_content/com.sap.pct/platform_add_ons/com.sap.caf.eu.gp.folders.gp/com.sap.caf.eu.gp.roles.runtime/com.sap.caf.eu.gp.worksets.runtime/com.sap.caf.eu.gp.pages.procinstance"/>
Change it to this:
<Property name="page" value="pcd:portal_content/com.sap.pct/platform_add_ons/com.sap.caf.eu.gp.folders.gp/com.sap.caf.eu.gp.folders.pages/com.sap.caf.eu.gp.pages.procinstance2"/>
This is because the process instance page which is called is located there in the pcd.
