Hi Matthias,
Although I am no experienced cocoon user, I may change your question by
the following sentence :
What is missing the current cocoon application ? Does cocoon 2.1.x fill
the gap ?
You may have to evaluate the cost of using a scripting language, but
having JS as Flow interpreter is due to the lack of languages supporting
continuations (correct me if I am wrong).
Benefits of FlowScripts are well explained here :
http://cocoon.apache.org/2.1/userdocs/flow/index.html
Moreover, JavaFlow exists in cocoon although I never used it. Have a
look on the apples block in the samples.
Hope this will help.

hi,
we are currently in the process of evaluating and/or restructuring an
existing cocoon application.
being a cocoon beginner i fail to see the benefits of
flowscript/javascript for the controller layer.
of course it is a good practice to have an explict controller layer
(control as in MVC),
BUT: why does it have to be in a scripting language?
imho, this has at least the following drawbacks
(mostly related to crossing the java-javascript-boundary in eclipse
during development):
-cannot refactor java-javascript
-cannot semantically search for usages of java classes in javascript and
vice versa
-cannot navigate (F3) easily between java-javascript
-cannot easily unit-test the javascript stuff with junit
-cannot debug javascript during run-time in the java debugger
-business logic (or technical framwork-related logic) tends to creeping
into the flowscript
i would much prefer to do everything in java itself.
so my questions are:
-am i missing anything?
-is there a recommended way to migrate the flowscript to java?
-will this change in cocoon 2.2?
any advice is greatly appreciated.
thanks
matthias
