Hi all,
In the "Custom Action", in the third part of the GMF tutorial
(http://wiki.eclipse.org/GMF_Tutorial_Part_3#Custom_Actions), a new Subtopic
node and a new Link (from the selected Topic to the new Subtopic) are
created. Following the example, I have been trying to do the same thing with
no success. In my case, the node is created but the link is not.
I also have tryed to create the link by means of
CreateViewAndElementRequest.getCreateCommand. In this case, the link is
graphically shown but the model lement is not created.
I do not know what other command or approach I can use.
I have been stuck on this stuff for some weeks, please, can anybody help
me??
Best regards,
Bego

We are in the same boat Begoña :) I have also been working on this for a

I successfully create node and link, the part that creates the link
looks like this in my case:
IElementType linkType = UemlbaseElementTypes.Class_SubclassRelation_4001;
CreateConnectionViewAndElementRequest connectionRequest = new
CreateConnectionViewAndElementRequest( linkType, ((IHintedType)
linkType).getSemanticHint(), selectedElement.getDiagramPreferencesHint());
ICommand createSubClassLinkCmd = new
DeferredCreateConnectionViewAndElementCommand(connectionRequ est,
shapeViewAdapter, new EObjectAdapter((EObject)
selectedElement.getModel()), selectedElement.getViewer());
Does this help?
If any one else is reading this, I really need help in "catching" the
newly created link/connection object.
Regards,
Tomas

Tomas, I do not understand!! My code is the same as yours (you can look at
it below). First, I create a new node (ProductRequirement in my case) and
then the link (DependenceTrace) between the current element, that is the
current ProductRequirement (my code is in the
ProductRequirementEditPart#handleNotificationEvent method) and the new
ProductRequirement. The only thing different is that I use "this" (to refer
to the current ProductRequirement) instead of "selectedElement".
What is the type of selecteElement in your case?
CompoundCommand commands = new CompoundCommand();
// types to be
reated --------------------------------------------------------
IElementType nodeType = ParamMMElementTypes.ProductRequirement_1001;
IElementType traceType = ParamMMElementTypes.DependenceTrace_3001;
// create the node --------------------------------------------------------
CreateViewRequest nodeRequest =
CreateViewRequestFactory.getCreateShapeRequest(
nodeType,
this.getDiagramPreferencesHint());
commands.add(catalogEditPart.getCommand(nodeRequest));
// create the trace --------------------------------------------------------
CreateConnectionViewAndElementRequest createTraceRequest = new
CreateConnectionViewAndElementRequest(
traceType,
((IHintedType)
traceType).getSemanticHint(),
this.getDiagramPreferencesHint());
// Source of the link: this, the current element
IAdaptable sourceViewAdapter = new EObjectAdapter((EObject)
this.getModel());
//Target of the link: the new created Requirement
IAdaptable targetViewAdapter = (IAdaptable) ((List)
nodeRequest.getNewObject()).get(0);
ICommand createTraceCmd = new DeferredCreateConnectionViewAndElementCommand(
createTraceRequest,
sourceViewAdapter,
targetViewAdapter,
this.getViewer());
commands.add(new ICommandProxy(createTraceCmd));
this.getDiagramEditDomain().getDiagramCommandStack().execute (commands);

Maybe you could send me your code?
I will compare it to mine, and see if I can solve your problem.

Tomas thank you very much for your time!!
My code is part of the handleNotificationEvent in ProductRequirementEditPart
class. What I want to do is create a new ProductRequirement (my node) and
link it (by means of a TraceDependence) to the current ProductRequirement
(the one that has changed some way).
My code is as follows:
CompoundCommand commands = new CompoundCommand();
IElementType reqType = ParamMMElementTypes.ProductRequirement_1001;
IElementType traceType = ParamMMElementTypes.DependenceTrace_3001;
// create the node. This
works!! --------------------------------------------------------
CreateViewRequest reqRequest =
CreateViewRequestFactory.getCreateShapeRequest(
reqType,
this.getDiagramPreferencesHint());
commands.add(catalogEditPart.getCommand(reqRequest));
// create the trace. Nothing
happens!!! --------------------------------------------------------
CreateConnectionViewAndElementRequest createTraceRequest = new
CreateConnectionViewAndElementRequest(
traceType,
((IHintedType) traceType).getSemanticHint(),
this.getDiagramPreferencesHint());
// Source of the link: this, the current element
IAdaptable sourceViewAdapter = new EObjectAdapter((EObject)
this.getModel());
//Target of the link: the new created Requirement
IAdaptable targetViewAdapter = (IAdaptable) ((List)
reqRequest.getNewObject()).get(0);
ICommand createTraceCmd = new DeferredCreateConnectionViewAndElementCommand(
createTraceRequest,
sourceViewAdapter,
targetViewAdapter,
this.getViewer());
commands.add(new ICommandProxy(createTraceCmd));
this.getDiagramEditDomain().getDiagramCommandStack().execute (commands);
Best regards,
Bego

No prob :) Our codes are quite different, but here is what I think your
code should look like:
///////////////////
private ProductRequirementEditPart selectedElement;
public void run(IAction action) {
CompoundCommand commands = new CompoundCommand();
IElementType reqType = ParamMMElementTypes.ProductRequirement_1001;
IElementType traceType = ParamMMElementTypes.DependenceTrace_3001;
CreateViewRequest reqRequest =
CreateViewRequestFactory.getCreateShapeRequest(
reqType,
selectedElement.getDiagramPreferencesHint());
// Get the Adapter to the newly created object
shapeViewAdapter = (IAdaptable) ((List) reqRequest.getNewObject()).get(0);
commands.add(catalogEditPart.getCommand(reqRequest));
selectedElement.getDiagramEditDomain().getDiagramCommandStac k().execute(cc);
CreateConnectionViewAndElementRequest createTraceRequest = new
CreateConnectionViewAndElementRequest(
traceType,
((IHintedType)
traceType).getSemanticHint(),
selectedElement.getDiagramPreferencesHint());
ICommand createTraceCmd = new DeferredCreateConnectionViewAndElementCommand(
createTraceRequest, shapeViewAdapternew EObjectAdapter((EObject)
selectedElement.getModel()), selectedElement.getViewer());
// Setup link compound command
CompoundCommand cc2 = new CompoundCommand("Create connection");
cc2.add(new ICommandProxy(createTraceCmd));
selectedElement.getDiagramEditDomain().getDiagramCommandStac k().execute(cc2);
}
public void selectionChanged(IAction action, ISelection selection) {
selectedElement = null;
if (selection instanceof IStructuredSelection) { IStructuredSelection
structuredSelection = (IStructuredSelection) selection;
if (structuredSelection.getFirstElement() instanceof
ProductRequirementEditPart) {
selectedElement = (ProductRequirementEditPart)
structuredSelection.getFirstElement();
}
}
}
///////////////////
Puh! I think that should work. I may be traveling to Spain (that is
where you come from, right?) this spring to collect data for my master
thesis. Looking forward to it (Norway is cold!)
Hope this helps,
Toams
