Strategy for updating the gmfgen model after having edited the ecore/ecore_diagram model [message #178680]

Hi!

I have a project where I need to edit the domain model during the
development process. In addition I have to customise the generated diagram
code using '@generated NOT' comments. Whenever I adapt the domain model,
manually update the genmodel, gmfgraph, gmfmap and gmftool models and
click 'Transform' on the Dashboard in order to regenerate the gmfgen model,
the code generator gets confused and throws away my customized code. Do I
have to update the gmfgen model manually as well? And why does it get
confused and throws away customised code if I regenerate the diagram code
after clicking on 'Transform'? BTW: I can reproduce the 'gets confused'
behaviour with a simple gmf model if it is a bug.

Cheers,
Florian

Hi Florian,

I am in the same situation as you are (i.e. a lot of customized code). If
I have to update the ecore model I proceed as follows:
1. update ecore diagram
2. validate it to be sure the changes are correct
3. reload genmodel (right-click on genmodel -> Reload...)
4. re-generate the code from the genmodel you need (model and edit code in
my case)
5. do the changes to gmfgraph, gmftool, gmfmap if needed.
6. validate gmfmap to be sure all changes are correct.
7. re-generate the gmfgen (right-click on gmfmap -> Generate generator
model...)
8. re-generate the diagram code from the gmfgen

In my case all customizations annotated with @generated NOT stay
persistent.

Hope that helps,
Marsha

You may also use 'Hide @generated code' filter in Package Explorer to
quickly find customized java classes.

Thank you both for your suggestions. The procedure Marsha described is
actually what I did so far. My problem seems to be the result of a bug.
Whenever I regenerate a java file which is currently opened in an editor
window, the EMF code generator for gmfgen produces strange results.
I'll confirm the problem and file a bug.

Cheers,
Florian

Hi Florian,

You are right, I forgot to mention that. I close all files every time I
re-generate the code. When a class is re-generated that was currently open
the code is quite a mess afterwards.

Greets,
Marsha

I sent a request to reopen bug #200527 which accurately describes the issue
we have.

Thanks for your help!
