Something very frustrating with myEclipse UML tool....

I am able to create UML from Java, but the tool is not letting me do the reverse! That is, after I have selected the classes I want to create, I then click Finish, and nothing happens!

Please help since I need to have this working for our design team by end of next week!

Many thanks in advance for your help here.

Marc,
Can you go to MyEclipse > Installation Summary > Installation Details and paste the information here fro me.

Do you have any messages being recorded under <workspace>/.metadata/.log file when the Java classes generation fails?

Can you switch to a new workspace and check if you are able to reproduce the issue. Can you paste a sample class here for me incase the problem persists.

For me, it isn't as if something is failing or giving an error.
I click Finish and the dialog just sits there as if I hadn't clicked.
It isn't doing anything obvious, the GUI doesn't freeze, I can hit Finish again or hit Cancel and it goes away.
It appeared as if it didn't do anything. However, the .log file did show the following dump:
!ENTRY org.eclipse.ui 4 0 2009-03-30 14:10:38.362

lupestro,
Can you please list the exact steps to help us reproduce this issue at our end,

I created a Java project and then generated a UML 1 model in it.
It's kind of hard to list the exact steps to build up a diagram with a pile of elements. I can send you the UMR.
However, once I have my diagram, I click the UML menu and select Generate Java.
For my Java output folder, it shows my project directory, but my src directory is one level down, so I edit the field to add /src to the end.
The source directory is, at this point, empty.
I then selected the classes to generate and pressed Finish. Nothing happened - except the exception I showed you.

I reloaded my workspace this afternoon and did the same thing today and got a very different result.
I got a dialog listing several types with problems regarding parameters or attributes without a declared type.
Since by the end of the day yesterday, I'd spent a couple of hours entering by hand and continuing with what would have been generated for me, I just added another source directory called gen-src, so I can fix up the problems, generate from the UML into there, and continue to play with this.
I can only assume that whatever went wrong yesterday was something it was doing along the way to producing the "types with problems" dialog.
Does that help?

Hey! I just noticed that my class diagram is now missing - just the sequence diagram (and the model information for the classes) remains. You want this UMR?

After correcting the issues in the model noted in the "types with problems" dialog, I was able to generate the Java classes.

Glad to know you got the issue resolved. Thanks for letting us know.

In response to your request via email, Nipun, the "types with problems" dialog was a dialog that popped up if the analysis encountered types in the model which had inconsistencies or issues of some sort. That's about all I can tell you about it. I haven't used this feature since then because of issues like that class diagram disappearing.

Thanks for getting back. Appreciate your help.
