Hi,

When I try to open a projectfile an error is given: An item with the same key already has been added (or something like this, the original message is in Dutch).

I copied the following info to the clipboard. Is there anything I can do to solve this? E.g. manually correcting the projectfile.

Exception information.

LLBLGen Pro version: v3.1. Build: September 30th, 2011

Exception details:

Message: Er is al een item met dezelfde sleutel toegevoegd.

Inner exception: <null>

I don't understand Dutch but if you could open a HelpDesk thread (which is private) and attach your .llblgenproj file, it would be useful in understanding the exception.

Did you receive this suddenly or do you remember something you did before (some model changes, db changes, an unusual refresh, upgrade, etc)?

Short after I tried Walaas answer on my question regarding the automapping of a decimal field (see http://www.llblgen.com/tinyforum/Messages.aspx?ThreadID=20482) I saved the project file. After that I could not open it. I only recall removing a foreign key and adding a new field for it. Than I deleted a relationship because the foreing key was no longer there and I added a new one to the new foreign key.

I'll open a case at the Helpdesk aswell.
