> There seems to be no intuitive way to concatenate strings in the value attribute of the set tag:
> <s:set name="a" value="%{'/jsp/'+#parameters.file}" />
> sets "a" to "/jsp/[Ljava.lang.String;@1bd2184", it also didn't help to enforce evaluation as a string:
> <s:set name="a" value="%{'/jsp/'+#parameters.file.toString()}" />
> Also in the Struts mailinglist no one could tell me, how to do that, even though I got an excellent reply:
> http://www.nabble.com/forum/ViewPost.jtp?post=13825946&framed=y
> I think there should be an intuitive way to do that, for instance it works in the text tag:
> <s:text name="/jsp/%{#parameters.file}" />
> The same one of the following would be logical for the set tag:
> <s:set name="a" value="%{'/jsp/' + #parameters.file}" />
> <s:set name="a" value="%{'/jsp/'#parameters.file}" />
