[jira] Created: (WW-2330) cancatenate strings in the value
attribute of the set tag
cancatenate strings in the value attribute of the set tag
---------------------------------------------------------
Key: WW-2330
URL: https://issues.apache.org/struts/browse/WW-2330
Project: Struts 2
Issue Type: Bug
Components: Expression Language
Affects Versions: 2.0.11
Environment: Tested on Debian Linux testing with Tomcat 6.0.14 and JBoss 4.
Reporter: Anton Pussep
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}" />

Musachy Barroso resolved WW-2330.
---------------------------------
Resolution: Not A Problem
This is not a problem. #parameters.file is an array as it was pointed out in the comments.

[jira] Commented: (WW-2330) unable to concatenate strings in the
value attribute of the set tag
Posted by "Ralf Fischer (JIRA)" <ji...@apache.org>.

Ralf Fischer commented on WW-2330:
----------------------------------
Isn't this "[L" the prefix which the toString() method of an array prepends?
If parameters.file is a String array, this expression should work:
<s:set name="a" value="%{'/jsp/'+#parameters.file[0]}" />
