Hi Zahid,
When does the exception come up? Does it
show up when you open the runtime workbench or is it showing up when you try to
create/move/delete an edit part? I had similar exception issues for which I
could not track the source; If you tell me which action led to this exception,
I can help you solve it.
Thanks & Gluck.

I am getting following
exception and struggling to find the source. I have modified LogicDesgner
sample application and would appreciate if some one can help where to catch
this exception and get stack trace.

Resizing figures.

hello
Bharath
After I make the following changes, it works,
though I
am not familiar with emf, ecore classes
such as EAttribute, EClass, and the
ENotificationImpl.
I try using PropertyChangeListener as my
ModelListener
to replace Adapter.
1. modify
NetworkXYLayoutEditPolicy.createChildEditPolicy
method
protected EditPolicy
createChildEditPolicy(EditPart
child) {
NetworkNodeEditPart childEditPart =
(NetworkNodeEditPart) child;
NodeFigure
rectangle = (NodeFigure)
childEditPart.getFigure();
return new
ResizableEditPolicy();
}
2. In the interface Node.java, add two new
methods
Dimension getSize();
void setSize(Dimension s);
3. In NodeImpl.java add
protected Dimension size_EDEFAULT = new
Dimension(-1,-1);
protected Dimension size=size_EDEFAULT;
public Dimension getSize() {
return
size;
}
public void setSize(Dimension dimension) {
Dimension
oldDimension = dimension;
size =
dimension;
if
(eNotificationRequired())
eNotify(new
ENotificationImpl(this,
Notification.SET, NetworkPackage.NODE_SIZE,
oldDimension, size));
}
and it is easy for you to modify other methods,
for
example, only add more "case return" following
the
method pattern.
4. In NetworkPackage.java, add something like
int NODE_SIZE=11; //randomly choose the int
EClass getSize();
5. In NetworkPackageImpl.java, add
public EClass getSize(){
return
(EClass)nodeEClass.getEReferences().get(11);
}
6. In SetConstrainCommand.java, add
two new fields:
private Dimension newSize;
private Dimension oldSize;
in execute() add part.setSize(newSize),
also add it to other methods.
7. In NetworkNodeEditPart.java, modify
refreshVisuals(), replace
Dimension size = new Dimension(-1,-1);
with Dimension size = getNetworkNode().getSize();
