Modified: src/scratchpad/schecoon/src/org/apache/cocoon/components/flow
JavaScriptInterpreter.java
Log:
Save the Rhino scope in the JSCocoon created object. Invalidate the
Environment and InvokeContext objects in the JSCocoon instance,
instead of removing JSCocoon from the scope.
(handleContinuation): Added. Make use of the Rhino scope saved in
JSCocoon to resume the processing.
