Reproducible: Couldn't Reproduce

Comment 1 Cedric Dumoulin

2010-07-08 08:03:41 EDT

Do you still have the faulty files (.uml+.notation+.di) ?
If you try to reopen these files, does the bug happen again ?

Comment 2 vathanamo.chey

2010-07-08 09:35:27 EDT

Since the bug occured, it happens again all the time if i try to re-open these files. I still have the faulty files but it contains confidential data. I don't have the right to add it.

Comment 3 Patrick Tessier

2010-07-09 08:26:42 EDT

Can you explain the scenario because I cannot reproduce it only with the trace.

Comment 4 vathanamo.chey

2010-07-12 10:05:10 EDT

That's the main point. This is a daily manipulation. I made too many change that i can't reproduce it.
The last things i want to do, are some features view of the system. This is just a simple requirement diagram. There was requirement bloc with <satisfy> and <verify> link to others classes.
After close and re-launch papyrus there was this class diagram  and some of it which has the stack trace describe above.

Hi

Can you provide us with your model because without any more information it will not be possible for us to go further investigating the origin of your pb.

Best... Sébastien Gérard.

Lost of two class diagrams after reopening Papyrus MDT. I got 2 different stack traces but it seems to be the same kind of error. 

The first stack trace is:

Each trace is depending on each diagram, this problem seems to appear when some association links are erased and when the class which had these associations is present in several diagrams in the same time.

Hi,

could you check the pb is still there?

thanks,

Hi,

This problem still exists in Papyrus MDT with build id 20100318-1801. I have not checked if this problem is corrected in newer version, but it seems that the reason of problem is the fact that when association between two classes is created then deleted, the property which is added by association in the class which owns association is not deleted in the same time. To solve this problem, properties added by the association have to be deleted manually in the class which owns association when association links are deleted. With this method, I don't have this problem. 

Kind regards.

Hi,

a priori I checked on my side today and the pb has been solved. The properties are not yet deleted (it is going to be solved today a priori) but however, we solved another bugs in parallel (a bug with delete on relationships) that has the side effect to solve the corruption bugs of this issue.
Tell me if is ok for you now.

Best... Sébastien.
