How to set relationCriteria for master panel with tree.
I have two objects: one is 'Category' and another is 'Orders'
I set 'Category' ListView as master panel for 'Orders' ListView'
The 'Category' is a 'Tree'.
I want the 'Order' ListView can show the records that 'Category Code' is the tree selected node and its children node. Please see 01.png.
But I don't know how to set the relationCriteria. Please see o2.png.
Can you help me?
