I'm using an advanced data grid which displays data in a tree structure format (parents and child nodes). The advanced data grid is a child component within a VBox and uses customized column renderers. I'm running into an issue where the advanced data grid is rebuilding (calling all the renderers again) whenever I move the mouse (focus) into the Advanced Data Grid component. The ADG component is binded to a data object. I'm expecting the ADG to rebuild when the data object it's binded to gets updated. In this case the bindable data object is not being updated. Why is the data grid rebuilding and is there a way to prevent this from occurring? I'm getting mouse over and mouse move events but they are not causing the ADG to rebuild.
