Sebastian:

Let me start by saying that Umbrello has the making of a *GREAT PROGRAM*  We have been searching high and low for this very type of application.  Have not been satisfied with the performance of ArgoUML.

With that said, I have run into problems running Umbrello.  I am running SuSE 8.1 and downloaded the RPM for SuSE, however it is version 1.1 Beta2 and perhaps this is where the problem lies...

I'm a bit hesitant to download and install the release candidate tarball as I have had disastrous results mixing source and RPMs on the SuSE distributions (a totally separate issue).

Anyway, I detected 2 problems/bugs and have 1 Enhancement request.

1.  Sequence Diagrams - When I make associations from one class to another, It appears that the logic between objects and associations is backwards...

Typical UML (consistent with Rational Rose, ArgoUML, etc...):

Class A  ---------- : test()  ---------->  Class B

-- Class A calls operation *test* in Class B

However with Umbrello the association logic is backwards and the resulting event actually infers that *test* is an operation in Class A...

Unfortunately, this is enough to make us not use Umbrello at this point in time...
 
2.  Collaboration Diagram - After I assign an association between 2 objects, I right click and select "Select Operation" and Umbrello crashes.
 
Another major downside for us.

We use both Sequence and Collaboration diagrams heavily when designing our apps, so these are necessary features for us.  I'm hoping that this has been fixed in the release candidate or at least is an issue with our setup.

Enhancement...

When Generating a class from Code, it would be nice if the initial values for variables would be included into the model.

I look forward to hearing from you...

Respectfully,
Bill Lewis
