Re: jsp:useBean problem (bug?) with Jasper

[Michiel Toneman <Mi...@bibit.com>]

Just replying to myself here, upgrading to 5.0.28 solved the problem.

If anyone else is having this problem with 5.0.25, please note that the 
jasper that comes with that release is 'borken'.

Sing with me:

happy, happy, happy, joy, joy, joy....
