Re: [aspectj-users] Calling proceed in a method

[Ashley Williams <ashley.williams@xxxxxx>]

Hi Andy,

Perhaps my use-case wasn't well described, but all I am attempting to do is to is refactor code from pieces of around advice, including the call to proceed(), to a common method. If there are implementation difficulties that mean this is too difficult to support in AspectJ then I am happy to use the worker pattern suggested by Ramnivas. Just wanted to make sure I wasn't missing a trick.

Many Thanks
- Ashley
