I just downloaded the 7.1 for Windows so I could take a look at the UML capability. I'm most interested in the reverse engineering of class diagrams. Unfortunately the first test I ran generated an error: Creation of element failed; parent has no name space.

I've tried adding -clean to the Eclipse start command btw and this made no difference.

Any recommendations? If this feature doesn't work, unfortunately I won't be able to purchase the licence.... shame because it looks good.

... if I reverse engineer each package individually, the error does not occur. Does this give a clue as to the root cause?

Hi,
Are you using UML1 or UML2 -- the UML2 tool is in a preview-release mode until 7.5 where we will have our final GA release of the tool with a ton of enhancements and improvements.

I just select the Reverse Engineer.... option from the UML menu. I downloaded the latest release of MyEclipse and I don't think I've ever had to select between UML 1 or UML 2. How do I check which is being used?

I just checked... I'm using UML 1. I started again:
1. Created new UML model selecting UML 1. I don't have the UML 2 option installed.
2. Selected Reverse Engineer from Java and accepted the default selection of all my source code.
3. Got the error.
