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. |

| 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. |
