I'm trying to use Table Per Hierarchy with discriminating with sub class with a join.

Example: http://nhforge.org/doc/nh/en/index.html ... criminator

Screen error when trying to update later from the database.

We cannot reproduce the problem at the moment. Please send us a test model and specify the following information:
1) the steps we should follow with your model to reproduce the issue
2) the text of the error in English
3) the exact (x.xx.xxx) version of your Entity Developer

Steps to Reproduce:

Create a new model, the type NHibernate;
Add a class with any property ('ll call Class1);
Add another class (Class2) inheriting from Class1;
Place in Class1 and Class2 the discriminator;
Add to Class2 Join one with some table;
Place in the propridades Class2 Join the created anteriorly;
Try an Update Model From Database;

Occurs the error: "The given key was not present in the dictionary."

Thank you for your report. We have reproduced the problem and are investigating it.

Thank you for the effort.

The bug with generating "The given key was not present in the dictionary" error in the Update Model From Database wizard is fixed in the new build of Entity Developer 5.7.342: http://forums.devart.com/viewtopic.php?f=32&t=29430.
