Hi,

I am playing with the shapes demo and trying to add Alignment.

My initial problem is that when I select two items the toolbar still remains
disabled.

The second problem is that when I right click for context menu no align menu
item is visible.

can anyone help?

thanks

Martin

The AlignmentRequest is handled by the XYLayoutEditPolicy. Make sure your
subclass isn't overriding any inherited functionality that handles this
request.

Thanks Steve you kinda helped ..

I hadn't overridden any of the align functionality
but it made me add a breakpoint on the getCommand() and found my constraint
command was the root of the problem. The canExecute() was restricting
requests. Adding RequestConstants.REQ_ALIGN_CHILDREN.equals(type) did the
trick!

One thing I have noticed thou' is that with the shape and the logic example
the align functionalty doesn't behave as expected. When I select align right
or align centre it always appears to align left. The Align top, bottom and
middle align has a similar problem!
