Diagram refresh Problem after reorder elements [message #516808]

Hi,

I have a custom action which perform changes to the EMF model underlying the diagram being edited in my GMF editor (e.g. MoveCommand).
These changes are not immediately reflected on the diagram after the action completes...I have to close/reopen the model in the editor for the updates to be displayed.
In the parent XXXCanonicalEditPolicy, I'm handling the syncronization of semantic elements with the corresponding notation elements.

The following code snippet I'm using to reorder the diagram elements.

@Override
protected void refreshSemantic() {
refreshNotationModel();
super.refreshSemantic();
}

private void refreshNotationModel() {
List<?> children = getSemanticChildrenList();
View parent = ((View) host().getModel());
EList<View> viewChildren = parent.getChildren();
jump: for (int i = 0; i < children.size(); i++) {
Object model = children.get(i);
for (int j = i + 1 ; j < viewChildren.size(); j++) {
View view = viewChildren.get(j);
if (view.getElement() == model) {
if (i + 1 != j ) {
ViewUtil.repositionChildAt(parent, view, i + 1);
continue jump;
}
}
}
}
}

The code above syncronize the diagram contents with the semantic model but somehow it doesn't reflect in the diagram editor(Canvas), might be the refresh problem.

Can you please suggest what I'm doing wrong here? Any help will be greatly appriciated.

Thank You.

Hi,

I think you should consider to override the refreshVisuals method
instead of creating your own.

Regards.
