Say you have components C1, C2, C3, and both C1, C2 goto C3. When C3 is
done, page will go back to the caller (C1 or C2).
You can actually pass the caller C1 or C2 (not the name but the actual
WOComponent object) to C3. In other words, you will have a
setCaller(WOComponent c) method in C3. Once C3 is done, just do a return
caller statement.
Of course there are many other ways. You can also use session to keep track
of the page(WOComponent) flow. Indeed, session does have a history to
remember the path.
