I have a drop down that changes the image path for Zoomify, the problem is the image doesn't change until the interface is clicked or dragged. imageCombo is a combo box on the stage. viewer is the Zoomify component on the stage. The path is set correctly as the image does change with user interaction. The combo box is triggering the change, I have output a trace and also debugged. Is there something I have to invalidate to get Zoomify to load the image?
