Hello,
If I properly understand, you use XYLayoutEditPolicy on an EditPart with=
a =
content pane layed out by DelegatingLayout ?
This should be the problem because in the code of XYLayoutEditPolicy, it=
=
is assumed that the layout manager is XYLayout and no other.
It's strange you don't get a classcastexception somewhere...
If you really want to use DelegatingLayout, perhaps you should write you=
r =
own ConstrainedLayoutEditPolicy...I don't know...
hope this will help,

Thanks for your answers.This is my another post:
My root figure is using DelegatingLayout to layout its children and
it extends from ConnectionLayer. We use Locator to locate the figure. Now
I want to move and resize my figure. The existing EditPolicy is
XYLayoutEditPolicy. I have use it.But it reports some exceptions and no
child can move and resize.So I think if I need to reinvent another
EditPolicy(DelegatingLayoutEditPolciy extends
ConstrainedLayoutEditPolicy)to move and resize my children.
Am I right?
If I must write,will I need to implement some key methods such as
getLayoutOrigin(),getConstraintFor(Rectangle) and getConstraintFor(Point).
Thanks in advance.
Daniel.
