Just guessing...
but first, does you multiple views of the same table inherits from one the other?
It may be that, if you want to have different views from the same table, define different childs for it (and not simply unrelated entities which may confuse EOM).
Hope it helps! let us know

I have found that EOModeler can create "overlapping" enterprise objects mapping to one table, so information in the table can be used in several different classes.

I have found this useful to present layout variations in my D2J app (each related EO represents a layout in a switch view). This works really well.

The problem is that when I create a new master EO, WO creates a new row in the database fine, but then tries to do it again for each related EO (using the same primary key). The result is an error saying the primary key isn't unique when it tries to insert another row.

I realise that I could put the information in separate tables, but this means manually adding key paths to the views for each field I want to have in multiple views.

Does anyone know a way to get D2J to update the row that already exists, rather than creating a new one?

Thanks,

Ray.
