I have a diagram, which is closed. Now I search for certain nodes and =
edges in this diagram and hide them via:
....
TransactionalEditingDomain te =3D =
TransactionalEditingDomain.Registry.INSTANCE.getEditingDomai n( "xxx");
te.getCommandStack().execute(SetCommand.create(te, view, =
NotationPackage.eINSTANCE.getView_Visible() , new Boolean(b)));
....
When I now open the diagram, everything worked fine. But when I do the =
same with a diagram, which is already open and then hide some elements, =
=
not all edges are invisible, some still remain. Now after closing and =
reopening the diagram everything looks fine again.
Cheers,
Dan

connections to invisible and reset them to visible, they are drawen from=

closing and reopening the diagram everything is ok. Does anybody know a =

workaround for this problem?

hi,
i'm dealing with this problem at the moment.
it seams that changing the visibility of semantic elements (e.g.
ShapeNodeEditPart) doesn't affect the
CannonicalEditPolicy/CanonicalConnectionEditPolicy which are responsible
for refreshing the connection edit parts.
i've read some other threads, but they are all about removing semantic
elements from diagram.
here is my scenario:
1. making elements invisible
node A is linked with node B via connection a->b.
hidding node A or B doesn't remove the connection a->b.
hidding noda A and B does remove the connection too.
2. making elements visible
make node A and B visible, also makes the connection visible. but like
daniel said, the connection is drawn from upper left corner to right
down direction. hide and show node A a second time (only node A!), or
reopening the diagram, resets the connection to the right location again.
any ideas?
andy

Hey,
is it still relevant to you? I detected the causing problem. The order
of setting the elements is important. First you have to set the nodes
visbile, then the edges. And when you're hiding the nodes and edges you
have to do it the other way aroung.
Cheers,
Dan
