Found a solution , i hope this can be a bug fix , looks like opening IMap
using new editor , it does not update MapGraphicContext viewportmodel , but
IMap. Changing "!context.getViewportModel()" to
"context.getMap().getViewportModel()" solved problem.
public MapGraphicContextImpl(final IRenderContext context,
Graphics2D destination) {
super();
setGeoResourceInternal(context.getGeoResource());
setLayerInternal((Layer) context.getLayer());
setRenderManagerInternal((RenderManager)
context.getRenderManager());
setMapInternal((Map) context.getMap());
vpg = new AWTGraphics(destination,
context.getMapDisplay().getDPI());
// add listener if doesn't already exist for layer
IViewportModelListener listener = (IViewportModelListener)
context
.getLayer().getBlackboard().get(BLACKBOARD_LAYER_KEY);
if (listener == null) {
listener = new IViewportModelListener() {
public void changed(ViewportModelEvent event) {
// need to invalidate image & refresh
the layer
if (renderManagerInternal.isDisposed())
{
setRenderManagerInternal(new
RenderManagerDynamic());
}
try {
//if
(!context.getViewportModel().isBoundsChanging()) { <-- old code
if
(!context.getMap().getViewportModel().isBoundsChanging()) { // <-- new code
context.getLayer()
.getBlackboard()
.put(MapGraphicRenderer.BLACKBOARD_IMAGE_KEY,
null);
context.getLayer().refresh(null);
}
} catch (Exception ex) {
ex.printStackTrace();
}
}
};
context.getViewportModel().addViewportModelListener(listener);
context.getLayer().getBlackboard()
.put(BLACKBOARD_LAYER_KEY, listener);
}
