Create node by double clicking [message #226329]

Hello,

I want to create a node and a link with a double click in another node. I
copied a similar code in part#3 of the tutorial (it's a
IObjectActionDelegate) in a AbstractTransactionalCommand but it doesn't
work as I want. The link is not created and the new node doesn't enter in
"Edit mode" and no errors appears.

So could anyone help me?

Thanks in advance.

Hello,
If the link points to an existing node, the link is created, however, if
the link points to the node created, the link is not created. This is an
extract of my code:

...
CompoundCommand cc = new CompoundCommand();
CreateViewRequest featureRequest =
CreateViewRequestFactory.getCreateShapeRequest(XXXElementTyp es.Feature_2001,
XXXDiagramEditorPlugin.DIAGRAM_PREFERENCES_HINT);
Command createFeatureCmd = ((EditPart)
projectEditPart).getCommand(featureRequest);
IAdaptable featureViewAdapter = (IAdaptable)
((List)featureRequest.getNewObject()).get(0);
cc.add(createFeatureCmd);

ICommand createSubTopicsCmd = new
DeferredCreateConnectionViewAndElementCommand(new
CreateConnectionViewAndElementRequest(
XXXElementTypes.RelationSelected_4003,((IHintedType)
XXXElementTypes.RelationSelected_4003).getSemanticHint(),
XXXDiagramEditorPlugin.DIAGRAM_PREFERENCES_HINT), new
EObjectAdapter((EObject) fatherElement.getModel()),featureViewAdapter,
fatherElement.getViewer());
cc.add(new ICommandProxy(createSubTopicsCmd));
...

I don't know what could be the problem. In an IObjectActionDelegate works
but not on an AbstractTransactionalCommand.

Where is the problem? Is this the right way to do what I want?

Any help is aprecciated.

Thanks in advance.

Hello,

Is it possible create a node in an AbstractTransactionalCommand and put it
in edit mode?

CreateViewRequest featureRequest =
CreateViewRequestFactory.getCreateShapeRequest(XXXElementTyp es.Feature_2001,
XXXDiagramEditorPlugin.DIAGRAM_PREFERENCES_HINT);
...
final EditPartViewer viewer = fatherElement.getViewer();
final EditPart elementPart = (EditPart)
viewer.getEditPartRegistry().get(topicViewAdapter.getAdapter (View.class));
if (elementPart != null) {
Display.getCurrent().asyncExec(new Runnable() {
public void run() {
viewer.setSelection(new StructuredSelection(elementPart));
Request der = new Request(RequestConstants.REQ_DIRECT_EDIT);
elementPart.performRequest(der);
}
});
}

elementPart value is always null. In the GMF tutorial part 3 works.
Could someone help me? I don't understand why it doesn't works.

Thanks.
