I have a problem with changing the model behind the diagram. What I am =
trying to do is inserting/populating a reference of the model. This has =
nothing to do with the diagram, since there will be no graphical element =
corresponding to this.
Here it is the code:
EditingDomain editDomain =3D protocolEditPart.getEditingDomain();
ResourceSet resSet =3D editDomain.getResourceSet();
EList resources =3D resSet.getResources();
Resource res =3D (Resource)resources.get(0);
if(res !=3D null) {
for(Iterator iter =3D res.getAllContents(); iter.hasNext(); ) {
Object o =3D iter.next();
=20
if(o instanceof ProtocolModel) {
ProtocolModel pm =3D (ProtocolModel)o;
=20
pm.setDataModel(mainPage.dataModel); // PROBLEM!
=20
break;
}
}
When I set the DataModel it gives me the error saying I have to use =
transactions... I read around some discussion on the commands subject, =
but I would need some straight/simple example (snippet) to see how to =
work with these commands.
Any help? Please!

Salut!
To read or write the model you must use commands. You don't need commands
if you read the model from an edit policy's getCommand().
To write to the model, you have to the wrap the code into an
AbstractTransactionalCommand, you'll find a full example below.
If you need to execute such a command from an action you will need a
ProgressMonitor. You can always use the NullProgressMonitor for this.
If you need to return such a command from an edit policy then you must
wrap it around an ICommandProxy.
Please note you cannot execute write commands from
GraphicalEditPart.getCommand() or from edit policies getCommand().
hope this helps!
vlad
public class ImportEntityCommand extends AbstractTransactionalCommand {
private static String label = "Import Block Interface Command";
private IFile file;
private Block block;
private Shell shell;
public ImportEntityCommand(Block block, IFile file, Shell shell) {
super(TransactionUtil.getEditingDomain(block), label,
getWorkspaceFiles(block));
this.block = block;
this.file = file;
this.shell = shell;
}
@Override
protected CommandResult doExecuteWithResult(IProgressMonitor monitor,
IAdaptable info) throws ExecutionException {
String filePath = file.getLocationURI().getPath().toString();
ArrayList<DesignUnit> dus = VHDLUtils.parse(filePath);
VHDLCompilationUnit compilationUnit = Bluenose2Factory.eINSTANCE.createVHDLCompilationUnit();
for (DesignUnit du : dus) {
if (du instanceof Entity) {
compilationUnit.getEntities().add( VHDLUtils.createEntity(
(Entity) du) );
}
}
ElementTreeSelectionDialog dialog = new ElementTreeSelectionDialog(shell, new AdapterFactoryLabelProvider(
Bluenose2DiagramEditorPlugin.getInstance()
.getItemProvidersAdapterFactory()), new AdapterFactoryContentProvider(
Bluenose2DiagramEditorPlugin.getInstance()
.getItemProvidersAdapterFactory()) );
dialog.setTitle("Import Entity Dialog");
dialog.setMessage("Please select the toplevel entity to import.");
dialog.setInput(compilationUnit);
dialog.open();
if ( dialog.getReturnCode() == Dialog.OK) {
Object[] result = dialog.getResult();
if (result.length > 0 && result[0] instanceof VHDLEntity) {
VHDLEntity entity = (VHDLEntity) result[0];
block.setBlkInterface(entity.getInterface());
}
}
return CommandResult.newOKCommandResult();
}

Everything looks fine, but i'm missing the call (execution) of this
command... How do I execute it from within my code?
Thanks.

I tryed the first solution, but, unfortunately, there is no result in =
the model file. Although is says the file was modified (the little * =
appears near the name of the file in the editor), when I close the =
editor and choose YES when it askes for saving the file, it gives me 2 =
identical errors: "An internal error occurred during:
"An internal error occurred during: "children update". =
java.lang.ArrayIndexOutOfBoundsException"
Any ideea of what could it be worng?

As you can see, it checks "next" if it's instanceof EObject. My "affected"
(to be saved) resource is a GMFResource, which seems to be "NOT instanceof
EObject"...

Don't pass the resource, pass one of the EObjects you're modifying.

if (resource != null) {
IFile file = WorkspaceSynchronizer.getFile(resource);
if (file != null) {
result.add(file);
}
}
}
return result;
}
at the line Resource resource = eObject.eResource(); turns my EObject back
into a Resource (GMFResource). Then, the line IFile file =
WorkspaceSynchronizer.getFile(resource); gives no file (null), so nothing is
modified in the end.
So we're back at the starting point... :-(

Can you describe your scenario so I can give a more informed opinion?
Do you have a bootstrapped diagram to start with? If not, bootstrapping
code is contained in the generated XXXDiagramEditorUtil.
Another case I can think of is when you have a model and want to attach to
it some other model elements created outside the gmf framework. For
instance, if you create model elements through the
XXXFactory.eINSTANCE.createXXXX methods, you can attach them to the gmf
model in a command that calls the corresponding set reference method.

Originally posted by: fbanica.soluta.net
So, I have a "ProtocolModel" and a "DataModel". I create a DataModel in a
GMF editor and the ProtocolModel in another one. (They both come from the
same meta-model)
What I am trying to do is "importing" the DataModel into the ProtocolModel.
The last one has a reference pointing the DataModel, so, from this point of
view there are no problems. If I make it "by hand" (meaning copying the text
in the XMI file) it's OK. The ProtocolModel editor has no problem with the
modified file.
The problem appears when I try to do it in the code. I made an Action
(IObjectActionDelegate) and inside this I made a wizard where the user can
choose the DataModel. From that I read the DataModel (dtMod) and then I want
to set the reference in the ProtocolModel:protMod.setDataModel(dtMod); This
is put in the doExecuteWithResult method of the AbstractTransactionalCommand
class, while the command and it's execution are in the performFinish()
method of the wizard.
Did you get the picture? Should I detail?
Thanks for spending a lot time with my problem...

The only problem I can think about is that if you have two editor windows
and they don't share the TransactionalEditingDomain.
Use protocolModelEditingDomain.getResourceSet().getResource(<<harcoded
data model uri>>, true);
And then call getContents() on the returned resource to get to the data
model which you pass to your command.

Hi, I'm back.
I think the main problem comes from the fact that my application is RCP and,
in this case, the file in the editor is open "form the file system" while
parameter passed as IFile "is saw as a Resource" (see also the "RCP
Application opens files and Eclipse Application opens resurces from the
workspace?" message in the list above)... As far as I could see in debug,
this Resource is not seen as "changed" from the transaction's point of
view... So, it doesn't happen anything in Execute.
Any other suggestions to resolve this?
Thank you,
Floppy

Originally posted by: fbanica.soluta.net
I did make an Eclipse Application (instead of a RCP one). Strange thing,
it's working now (using cmd.execute(new NullProgressMonitor(), null); ),
but, when I close the second workbench, I get 3 errors:
1. Asynchronous viewr update: error
2. children update: An internal error occurred during: "children update".
java.lang.ArrayIndexOutOfBoundsException
3. children update: An internal error occurred during: "children update".
java.lang.ArrayIndexOutOfBoundsException
2 and 3 are the same, indeed, but they are displayed just like that...
So, it seems that there is a problem when working with the RCP application
(the file is not updated at all), but also with the Eclipse application it
gives me those 3 errors... What shal I do next? Please help.
