hi,I have created my GEF example according to the Logic Example,but when I
drag my connection from paletteviewer and put it on the selected
anchor,the connection location always begins from the left corner of the
editor and ends
on the selected anchor.I don't know why it works in Logic example but it
cannot work in my example?

See NodeEditPart, and your implementation (or lack of)
getSourceConnectionAnchor(Request).
this method is used during feedback, as opposed to the other similar message
which is used when a connection editpart exists.

ShapeEditPart(the same as the LogicEditPart) and then in class
RoundedRectangleEditPart(it is a subclass of ShapeEditPart) I let the
getSourceConnectionAnchor(Request)and getTargetConnectionAnchor(Request)
return null just like it does in the Logic example.Will I implement the
two methods in class RoundedRectangleEditPart?

It doesn't return null in the Logic example:
public ConnectionAnchor getSourceConnectionAnchor(Request request) {
Point pt = new Point(((DropRequest)request).getLocation());
return getNodeFigure().getSourceConnectionAnchorAt(pt);
}

I'am sorry to write the wrong code.After the correcting,it makes
progress.there are mutiple connections .
But still some problems like I asked the forum.Its beginning is still from
the left corner of the editor.
Sorry to bother you, Randy!I must implement the example.
I implement the getSourceConnectionAnchor's two methods and
getTargetConnectionAnchor's two methods in the ShapeEditPart(just like the
LogicEditPart in the Logic example.And in the subclass
RoundedRectangleEditPart of ShapeEditPart(just like the CircuitEditPart)I
do not implement the above four methods.
the rest code is the same as the CircuitEditPart of the Logic example.
I checked the rest but found no errors.
Lots of thanks!
