The widget I've developed opens a SubWidget in a panel and uses the dojo border container, content pane, and accordion pane to display a dgrid and some tools. When moving the widget into the web app builder framework I am experiencing a weird issue that is hard for me to diagnose.
Before the Constructor method is fired, the other icons in that upper panel move into the map area adjacent to where the panel is about to be rendered.
This type of issue is very hard to track down but is most always a custom css issue. I am not sure what other help I can provide but start commenting out stuff till you find the culprit.
