------------------------------------
This is related to STS-514 (but is a different bug).
> variable evaluation in tag attribute with UseActionBeanTagExtraInfo
> -------------------------------------------------------------------
>
> Key: STS-601
> URL: http://www.stripesframework.org/jira/browse/STS-601
> Project: Stripes
> Issue Type: Bug
> Components: Tag Library
> Affects Versions: Release 1.5
> Reporter: Chaf
> Assignee: Frederic Daoud
>
> Consider the following snippet from a given jsp file:
> <c:set var="binding">MyAction.action</c:set>
> ...
> <stripes:useActionBean binding="/stuff/${binding}" var="actionBean" />
> I am simply binding an action bean to /stuff/MyAction.action
> During jsp compilation, the stripes:useActionBean tag is validated through
> UseActionBeanTagExtraInfo
> Unfortunately, this results in a ClassCastException because of the following
> statement in the validation in class UseActionBeanTagExtraInfo:
> String var = tag.getAttributeString("var");
> Indeed, debug shows, for some reason that I haven't investigated, that the
> value of the "binding" attribute is an object, and I cannot get any more
> information about it. Looks like the ${binding} variable hasn't been properly
> evaluated yet. And it cannot be cast to a String.
> Note that:
> 1. the problem is solved by not using a variable: <stripes:useActionBean
> binding="/stuff/MyAction.action" var="actionBean" />
> 2. I had no problem with stripes 1.4.3 (which did not feature the
> UseActionBeanTagExtraInfo)
> Regards,
> chafrilo
