Hi,

I have a GraphScene with two LayerWidgets mainLayer where I put all the LabelWidgets and connectionLayer where I have the ConnectionWidgets.

mainLayer = new LayerWidget(this); addChild(mainLayer); connectionLayer = new LayerWidget(this); addChild(connectionLayer); mainLayer.bringToFront(); this.getActions().addAction(ActionFactory.createZoomAction());

My problem is that in certain graph the lines are painted over the labelwidget making difficult to read the label.

See the following image for an example

[image: 20090430-mp1fn6j3kka869caaejw1achu3.jpg]

When I try to change the order of the LayerWidget (either changing the order of the addChild calls or invoking mainLayer.bringToFront()) I get the following exception when trying to show the GraphScene. It seems that connectionLayer has to be always on top of mainLayer. Have anybody any idea on how to solve/workaround this?
