Bug 456080

Description Pierre-Charles David 2014-12-23 09:29:43 EST

+++ This bug was initially created as a clone of Bug #453036 +++

Eclipse Luna : 4.4.0
Sirius : 1.0.1
Ecore tools : 2.0.0.201406112035

When reconnecting, a warning "The semantic model was not correctly updated by the reconnect tool, the diagram part of the reconnect cannot be done" sometimes pops up in Error log. The reconnection is cancelled and the command stack is flushed (no Ctrl-Z anymore).

This behaviour is easily seen using ecore tools.

Steps to reproduce : 

1 - import the given test project
2 - open the class diagram
3 - try some reconnections
4 - sometimes the error pops up in error log and the reconnection is cancelled.

Cases in which I get the error on my computer :

Case 1 :
- from the starting point (reference betwenn EClass1 and EClass2)
- try to reconnect the Eclass1's side to have an edge between EClass3 and ECLass2 => error

Case 2 :
- from the starting point (EClass1 <-> Eclass2)
- do a few reconnections which work (EClass1 <-> Eclass3, EClass1 <-> EClass4, EClass2 <-> EClass4, EClass3 <-> EClass4)
- now try to do EClass3 <-> Eclass2 => Error.
