Missing help for Parent-Child-Subchild problem
We produce printers. Each printer has a printerhead and each printerhead can be another type. So I have three tables, which I'll combine in one view.
Thanks a lot for the property useCombination=1. With help of an MM-Table for printer and Printehead I can now select or create a new record. To integrate the type-table I make a second MM-Table for printerhead and type. But now...there is a problem:
I see the printer...I see the printerheads, but there is always no title for type. The list with the type-records is correct and I can make a relation to the printerhead, but after saving the type-title disappear and in MM-Table stands a zero in the field "type".
So...how to make a parent-child-subchild-relation?
