Hi,
When initialized a diagram file from model file, the generated
".xxx_diagram" only contains the root diagram itself like following:
<xml>
<diagram>
</diagram>
Is there a way to generate a complete diagram file having all diagram
elements in it, as following:
<xml>
<diagram>
<node1/>
<node2/>
</diagram>
Regards,
Hao

Hi Alex,
Thanks for letting me know this method. The reason why I asked this
question is that in my application which uses GMF diagram partitioning,
when I initialized a diagram and opened it, if it contains a sub-diagram
and I double-clicked to open the sub-diagram and save it, the
"HintedDiagramLinkStyle" style of the sub-diagram node (actually the
node it self) is not persisted, so the next time I open the same
sub-diagram, a new diagram is generated in the notation model and it is
an unexpected duplicated diagram.
I think it is a bug because my diagram is very simple and I can easily
reproduce this issue (I'm using GMF2.1.0M6a, also tried on previous GMF
versions). I tried the method you provided in XXXInitDiagramFileAction
and XXXNewDiagramFileWizard, unfortunately till now I can't get the
sub-diagram node persisted, I'm going to invest more time on that.
It would be great if you can point out where I should modify on
generated codes or some glues on that.
Regards,
Hao

Hi Alex,
Your codes worked, till now I havn't found the issue any more. It is
great, thanks!
I submitted an bug entry for this:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=232229
BTW, several months ago I had another bug entry about diagram
partitioning (which is also an issue in the project we're developing),
do you happen to have any thouhgts on it?
