This is what I did to solve the issue:
In "Panel C" class:
// Return button.
List crumbs = getBreadCrumbModel().allBreadCrumbParticipants();
IBreadCrumbParticipant p = null;
for (Object obj : crumbs) {
p = (IBreadCrumbParticipant) obj;
if (p instanceof PanelB) {
break;
}
}
...
final IBreadCrumbParticipant participant = p;
BreadCrumbLink returnBtn = new BreadCrumbLink("returnBtn",
getBreadCrumbModel()) {
@Override
protected IBreadCrumbParticipant getParticipant(String
componentId) {
return participant;
}
};
form.add(returnBtn);
Not sure if it is the best solution, but it works...
Thanks,
Daniel
