Hello,
I have tried to repeat a tutorial which is described at
http://www.elver.org/hibernate/gmftutorial/tutorial1.html . And have got
"java.lang.IllegalStateException: Cannot modify resource set without a write
transaction" from the action "Initialize mindmap_diagram diagram file"

Any ideas?

Thanks
Kirill

Hi,
Yes this is an issue because the HibernateResource sends out notifications when loading content from
the database. This can be disabled by passing the DISABLE_NOTIFY option when loading a resource.
Which is not directly possible in the way the resource is used here (the load action is called
implicitly). I have entered a bugzilla for this and will look at this issue later.

As an intermediate workaround you can replace the part in the try catch (line 117 in
MindmapInitDiagramFileAction.java) with the following code:

Resource res = new HibernateResource(URI
.createPlatformResourceURI(mySelectedModelFile
.getFullPath().toString()));
HashMap options = new HashMap();
options.put(XMLResource.OPTION_DISABLE_NOTIFY, "true");
res.load(options);
resourceSet.getResources().add(res);

// Resource resource = resourceSet.getResource(URI
// .createPlatformResourceURI(mySelectedModelFile
// .getFullPath().toString()), true);
diagramRoot = (EObject) res.getContents().get(0);

Note that the old call to resourceSet.getResource is commented out.
