Child EditPart Problems - XYLayoutPolicy?? [message #219095]

Hi,

I have the main diagram EditPart.
This contains EditParts (A) which can contain other EditParts (B).

(A) has a XYLayoutPolicy that implements
createChangeConstraintCommand ()
getCreateCommand ()

The problem I have is this:
I can add instances of (B) to (A); however, (B) will always locate itself
at the top left position of (A) when added. I can move (B) to other
locations in (A), which will cause a resize of (A) if necessary. When I
add another instance of (B), all of the other (B) child EditParts and the
new child EditPart move back to the top left position of (A), and (A) will
resize itself?

Regards,
Mark.

Sorry, fixed this. I was not setting the location in the model before
creating the child editparts.
