Hi All,

I am newbie in Graphiti and modeling world.

I'm trying to store my Graphiti Diagram, with all objects that it contains, in EMFStore, through emfstore API.

Can I do this at all? And if I can, how?

I tried to do this in resourcesSaved method of DiagramTypeProvider, but i got "Commit cancelled by checksum error handler due to invalid checksum" error.

Here is part of my code

System.out.println("Client starting...");

ESWorkspace workspace = ESWorkspaceProvider.INSTANCE.getWorkspace();

workspace.addServer(Application.localServer);

for (ESServer existingServer : workspace.getServers()) {
if (existingServer != Application.localServer) {
try {
workspace.removeServer(existingServer);
} catch (ESServerNotFoundException e) {
e.printStackTrace();
}
}
}

final ESLocalProject demoProject = workspace.createLocalProject("DemoProject");

for (ESLocalProject existingLocalProject : workspace.getLocalProjects()) {
if (existingLocalProject != demoProject) {
try {
existingLocalProject.delete(new ESSystemOutProgressMonitor());
} catch (IOException e) {
e.printStackTrace();
}
}
}

String username = "super";
String password = "super";
ESUsersession usersession = Application.localServer.login(username, password);

ESRemoteProject remoteDemoProject = demoProject.shareProject(usersession, new ESSystemOutProgressMonitor());

for (ESRemoteProject existingRemoteProject : Application.localServer.getRemoteProjects(usersession)) {
if (!existingRemoteProject.getGlobalProjectId().equals(remoteDemoProject.getGlobalProjectId())) {
existingRemoteProject.delete(usersession, new NullProgressMonitor());
}
}
TransactionalEditingDomain editingDomain =
TransactionUtil.getEditingDomain(diagram);
editingDomain.getCommandStack().execute(new
RecordingCommand(editingDomain) {

@Override
protected void doExecute() {
demoProject.getModelElements().add(diagram);
}
});

// Goal goal = GoalsFactory.eINSTANCE.createGoal();
demoProject.commit("Diagram commited", ESCommitCallback.NOCALLBACK, new ESSystemOutProgressMonitor());

Any help is appreciated

Djorde,

I'm not familiar with EMF Store, so I don't know how they handle saving.

But I assume they have a special kind of resource they need to connect to
the workspace. So the easiest approach would be to create such a resource
instead of a standard EMF resource and add your new objects to that
everywhere you create EObjects (e.g. in create features).

The diagram itself (root object) needs to be created outside of the editor
in an EMFStore resource and the editor should be started with a URL that
should point to this object. The child diagram objects should then
automatically be stored in the same resource using the default Graphiti save
mechanism.

As I said I'm not familiar with EMFStore and I haven't tried that.

Michael

Hi Djorde,

I have the same problem like yours. I need to display my emf models in diagram editor, and I also need to store Graphiti Digram file in EMFStore.
I would like to ask you, did you resolve this problem? Could you tell me please how?

Any help is appreciated

Best regards, Ruslan
