Hello,

I couldn't find any "getting started"-like documentation and I have trouble even with the most simple things in EclipseUML. For example, I can't create objects in a sequence diagram.

Is there any basic documentation on EclipseUML anywhere?

Thanks in advance,

Best regards

I had a look at the workspace .log and it says:

Hello,

I have the same problem. I'm trying to use Omondo sequence Diagrams.

I get an "Unhandled event loop exception"
and then further error messages:

Failed to execute runnable (java.lang.NullPointerException)
org.eclipse.swt.SWTException: Failed to execute runnable (java.lang.NullPointerException)

at org.eclipse.ui.internal.ide.IDEApplication.run(IDEApplication.java:96)
...

Nearly the same happens with class diagrams: I can add a first class without problems, adding a second class results in the same errors as above.

I have tried this with with a fresh installation
eclipse.buildId=M (on WindowsXP, JVM= JRE1.4.2_05)
and a virgin workspace with the results above.

I had also tried before with Ecplise 3.0.0 (and automatic update of ciomponents to 3.0.1), and with Eclise 3.1M ... . Also with the same effect.


The weird thing is, that my colleagues installation (fresh eclipse 3.0.1) works without problems.

Any idea what I have made wrong?

Hello,

It seems I have solved my problem.

For some unknown reason I have two suboptions in the "new" Dialog:
- EMF Diagrams and
-UML Diagrams

Both suboptions seemed to offer the same diagrams, but it turns out that there a tiny but important differences as e.g.
- EMF Sequence diagram vs.
- UML Sequence diagram

EMF Diagrams show the effects described in the posts before, UML diagrams work (at least as far as I have tried them).

Remains the question: What are these damned EMF Diagrams?
