Problems with multi-page editors [message #115372]

Hi,

I have following problem: I created a multi-page editor with two
diagrams, but whenever I insert the "related diagram" reference and
generate the source code, the main diagram is "destroyed". "destroyed"
means that the main diagram is still working but I can't place nodes
anymore. Before I "related" both diagrams it was working. Additionally
the palette of the main diagram is mixed up with the sub-diagram's
palette. When I place the mouse cursor in the main diagram a bubble with
all elements I can create there opens. But all elements in that bubble
are disabled. When I open an old diagram where nodes have already been
placed, the double click feature works.

What I did (I am using GMF 2.0M5uh):

- create the main editor (genmodel, gmftool, gmfgraph, gmfmap)
- create the sub-editor (gmftool, gmfmap; use genmodel and gmfgraph of
main diagram)
- edit gmfgen of sub-editor:
- Gen Editor Generator
* Model ID (editor id)
* Package Name Prefix (main-package for sub-diagram)
- Gen Plugin:
* ID (name of project folder)
* Name (plugin name)
- Gen Editor View:
* ID: is automatically set when I change the package name
- Gen Diagram.Editor
* Editing Domain ID: is automatically set when I change
GenPlugin.ID
- edit gmfmap of main editor:
* insert "related diagram" reference to the sub-editors gmfmap
- edit gmfgen of main editor:
- Open Diagram Behaviour
* Diagram Kind: GenEditorGenerator.ModelID
* Editor ID: GenEditorView.ID
- generate source code of both diagrams

I tried this several times and I got always the same problem described
above. Have I missed to set some attributes or is it just a bug?

Do I have to set the "Package Name Prefix" attribute to another value
compared to the main diagram or do they have to be the same?

I have absolutely no idea what could be wrong. Thanks a lot in advance!

There is also another bug: when I set the "diagramKind" and "editorID"
attributes in a gmfgen file and regenerate it from the corresponding
gmfmap file, the values of both attributes are discarted and one has to
set them again.

Regards,

Stefan

Hello Stefan,

So, once more: the problem appear only ater setting "related diagrams" property
and regenerating the code? (without this property and with all the same options
generated code works well in multy-page editor?)

That's really strange - AFAIKSee from the code these properties should be
preserved if changed by user.

Your remark was helpful. My problem had nothing to do with the "related
diagram" attribute. I finally found out that one has to set the
GenEditorGenerator.DiagramFileExtension attribute of the sub-editor to a
different value than that of the main editor. Otherwise the editor
behaves pretty strange. Perhaps this value should be set automatically
to a valid value by the generator.

I recognized this several times. I think it is a bug. Perhaps someone
else can can confirm it.

Stefan

Unfortunately generator does not know anything about your second diagram,
so this property can not be automatically modified – you should made it unique
in scope of all the GMF editors..

Can you try to localize it and provide us with steps to reproduce (m.b. with
some particular models)?

Hello there,

is there any tutorial or article speaking about how to make 2 or more
diagrams in the same project (something like Stefan did)?

Thanks,

Hello FLORIN,

You can realize what you should modify from this document: http://wiki.eclipse.org/index.php/GMF_GenModel_Hints
