Filter issue - when lookup is using IsTree and TreeParentMember parameter

I’ve GUID entity field with DefaultLookup. When the lookup has IsTree set to true and filled parameter TreeParentMember, you cannot filter that field via clicking the + symbol to select value from list. It is used in ERP lookup ProductCategory.

Which version are you using?

Have we implemented the tree view based lookup?

As far as I know, it is not implemented.

Master version 2021.2.0.2148

How does the dropdown look in the GUI? I think tree view drop down is not implemented.

There is no dropdown on that column in the GUI form filter.

In this case the dropdown can be remodelled to support a 2-level hierarchy. Otherwise it is not used anywhere else. We won’t implement tree-drop down now and wait for a commercial opportunity to do so.
