[news.eclipse.technology.emft] [EMF Compare] Comparing failed for custom

[Sorin Fagateanu <cyron_16@xxxxxxxxx>]

Hi,

I am having some problems using the EMF Compare tool when I compare 2 extended uml models. This is the error I receive :

Comparison  throught EMF Compare failed.
Reason:
Value ' mailto:x.NoteImpl@123 ( name :<unset> ...etc)' is not legal.
Next is displayed the line and column in the A.myuml file where the error happens.

A.myuml file is a model containg uml2 elements and also elements from a custom metadata (this being extended from uml2).

I am having difficulties find out why this error happens because it apears only a pop-up message and nothing in error log is entered.

Does anybody else has encountered this type of error? If yes can you please guide me?
I would also like some hints where could I put some breakpoints to find out what is the source of the error.

Thank you in advance for your help,
Sorin.
