Selectwdg question

[EricTsuei]

Hi
I have a problem when using selectwdg
I am still using tactic4.5 v1

I can't use this expression in selectwdg

Code:

@GET(vfx/template["type",@GET(.process)].code)

   

I have  2  types of my sobject, name vfx/template
   
I want to display the drop-down menu  differently depending on the task's process
