I can't use the "lookup record" function in my window.
I have set all the column that I want to "selection column". Then when I go to the window and I try to use the lookup record, I see all the column I've set but when I click on a combobox the lookup window directly closed, I can't go to the advanced search tab too.

I've try to check/uncheck the readonly checkbox in the window configuration with no result.

This problem exist with my table not with existing table. Must I configure something else that just "selection column"?
