Hi everybody,

I have a problem when I use EEF with an Interface and SubTypes, when I use the model bellow.

index.php/fa/11565/0/

I have added edition element linked to a view which dispaly Advanced Table Composition widget, but when I try to create a new SequencingRelation, I have the following problem :

But I can edit it when I have create it with New Child in the tree view.

So, I have try to do the same thing on a simplier model (see the attachment), to see if it was caused by the use of inheritance but when I choose to create an eleve, everything work fine, whereas, when I choose to create a prof, the properties aren't display. That problem appears only during the creation, and I can edit my object prof normally as you can see.

index.php/fa/11566/0/

When I try to create a prof I have in the console:

This time my console display:

Sorry for the french example, and for my bad english.

I don't think that the two problem are linked, but the problem I faced with my example surprised me.

Any help will be great,

Thanks,

Aurélien.
