Selection problem

Hi Guys,

I have 2 subgraphs whith in another subgraph (see picture). When i constructed this model i set the inner subgraphs to: Selectable=false, moveable=false and editable=false but still the user can select, drag and edit the inner subgraphs.
do you have any suggestions?
Thanks,

p.s. here is the actual code:
this.LeftSequenceBlock = new UIEntitySubGraph(this.ObjectState.FirstChild.NextItem.NextItem, "Thread 2");
this.LeftSequenceBlock.Selectable = false;
this.LeftSequenceBlock.Movable = false; this.LeftSequenceBlock.Collapsible = false; this.LeftSequenceBlock.Label.Selectable = false; this.LeftSequenceBlock.Editable = false;

this.Add(this.LeftSequenceBlock);
this.LeftSequenceBlock.Init(true);
this.RightSequenceBlock = new UIEntitySubGraph(this.ObjectState.FirstChild.NextItem, “Thread 1”);
this.RightSequenceBlock.Selectable = false;
this.RightSequenceBlock.Movable = false;
this.RightSequenceBlock.Collapsible = false;
this.RightSequenceBlock.Editable = false;
this.RightSequenceBlock.Label.Selectable = false;
this.Add(this.RightSequenceBlock);
this.RightSequenceBlock.Init(true);
this.EndNode = new UIEntitySequenceEnd(this.ObjectState.FirstChild.NextItem.NextItem.NextItem);
this.Add(this.EndNode);
this.Doc.MakeLink(this.RightSequenceBlock.BottomPort, this.EndNode.TopPort, false);
this.Doc.MakeLink(this.LeftSequenceBlock.BottomPort, this.EndNode.TopPort, false);
this.ReparentAllLinksToSubGraphs();

in Demo1, the GoSubGraph that has “inner” SubGraph. If I set “inner” to moviable=false… it isn’t draggable.
