Connections are not shown [message #198018]

Hi again,

I'm still trying to show connections among the nodes of the application
I'm working on. I will give you a brief overview of my architecture so
that you can help me to spot the problem.

- There is one GraphView which extends LayeredPane (so its layout is
StackLayout by default)
- Inside this GraphView there is one NodeLayer which extends Layer and set
its layout to ToolbarLayout.
- Inside this GraphView there is also a ConnectionLayer
(org.eclipse.draw2d.ConnectionLayer)

After adding those 2 layers (Node and Connection) into the GraphView, the
application populates the NodeLayer with many Nodes.
After putting all nodes into the NodeLayer, the application creates
connections (PolylineConnection) among them and then add those connections
into the ConnectionLayer.

The result is that all the connections are added to the same point. I
printed the con.getStart() and con.getEnd() values and they are set to
(0,0) and (100, 100) respectively. All of them.

My nodes are displayed without any problem but all the connection are
drawn on the same place.

Could someone please help me to solve this problem?
Any help is appreciated. Thank you very much.

Best Regards
Cleverson Schmidt

Is it possible that the problem lies in the layout of my NodeLayer?

By the way, this is how I am linking my layers:

public GraphView(Model model) {
conLayer = new ConnectionLayer();
conLayer.setConnectionRouter(new ManhattanConnectionRouter());
nodeLayer = new NodeLayer();
add(conLayer);
add(methodFigureLayer);
buildMethodsCallGraph();
}

The buildMethodsCallGraph puts many nodes in the NodeLayer and afterwards
creates the connections between them.

Please help
