I created a Tab with an included tab (header/rows structure).
On the subtab (included tab) there is a button for every row. This button should trigger a java process (java class, extending SrvProcess). When the user clicks on this button, the process is not invoked, because i think there is a bug on the GridTab class.
String callout = field.getCallout();
is called with a null field, because the field is refered to the main panel and not the included panel.
