Hi everyone 
i have a little problem that when I try to load the form from the worklist 
the worklist always pass the parameter with value =0 
the link will be as below

http://k2/Runtime/Runtime/Form/EdittingMangerApproval/?_State=&Editting_PK=0&SerialNo=12345

the Editting_PK=0 should conten the parameter not 0 

also when i change the Editting_PK=0 to be Editting_PK=15

http://k2/Runtime/Runtime/Form/EdittingMangerApproval/?_State=&Editting_PK=15&SerialNo=12345

the data will be loaded 

so how can i fix this problem
