Description

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:

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}

" />
