James Holmes updated WW-2174:
-----------------------------
Fix Version/s: Future
> Prepare interceptor: prepare methods invocation order should be reversed
> ------------------------------------------------------------------------
>
> Key: WW-2174
> URL: https://issues.apache.org/struts/browse/WW-2174
> Project: Struts 2
> Issue Type: Improvement
> Components: Interceptors
> Affects Versions: 2.0.9
> Environment: xwork
> Reporter: Nicolas Romanetti
> Fix For: Future
>
>
> Hello,
> before the actionMethodName() is called, the prepare interceptor calls
> prepare<ActionMethodName>() and then prepare()
> First usage pattern is: I do not need prepareXxxx, I use only prepare
> 2d usage pattern is: I do need prepareXxxx, but I do not need prepare at all,
> so my prepare method simply does nothing
> 3d usage pattern is: I need both
> Usage patterns 1 and 2 are OK, however the 3d pattern usage is in my opinion
> not well supported by this interceptor.
> You need such a feature when your action class regroups several action
> methods and you need to factorize some preparation.
> In my opinion, the factorized preparation, prepare(), should be called first
> and not after the specialized preparation, prepareXxx().
> Indeed, prepare is not supposed to be aware of the action method called, so
> it cannot really do something useful in between
> prepare<actionMethodName>() and the actionMethodName() itself.
> However, if called before, the prepare<actionMethodName>() could benefit from
> it.
> I suggest to simply reverse the calling order. I understand this would be a
> major change. We could simply make it configurable...
> Regards,
> Nicolas.
