Frederic Daoud commented on STS-514:
------------------------------------
I got bitten by this bug today and it hurt :(
In a nutshell, using <s:useActionBean beanclass="${something}"/> results in a
very hard-to-track down JSP error. It's all UseActionBeanTagExtraInfo's fault.
I tested removing UseActionBeanTagExtraInfo and that solves the problem. What
is that class good for anyway, and are its benefits worth the cost of not being
able to use something dynamic in the beanclass attribute of useActionBean?
