Description

There's actually a whole class of bugs like this; the repro below is only one example.

Repro:

• Add the attached page flows to a webapp, build, and hit /first/Controller.jpf.
• Click the "goNested" twice quickly.

You'll see the following stacktrace on the console:

org.apache.beehive.netui.pageflow.EmptyNestingStackException: Empty nesting stack for returned action nestedDone from page flow /nested/Controller.jpf.
