Editable search grids and Poly Items that are Relationship Items

Hi community,

without ever having tested this one I would say - no.

Polyitems itself aren´t real items. They just linked together other existing data. If you take a look at polyitems on database level, they aren´t a table but a function.

But that doesn´t mean that what you want to do is impossible. But you probably have to replace the original used action elements with custom ones that bypass the PolyItem ItemType.
