>                 Key: TILES-338
>                 URL: https://issues.apache.org/struts/browse/TILES-338
>             Project: Tiles
>          Issue Type: Bug
>          Components: tiles-jsp (jsp support)
>    Affects Versions: 2.1.0
>            Reporter: Zach Bailey
>             Fix For: 2.1.1
>
>
> In AddAttributeTag#doAfterBody:
> /**
>      * Save the body content of this tag (if any).
>      *
>      * @return It returns <code>SKIP_BODY</code>.
>      */
>     public int doAfterBody() {
>         if (value == null && bodyContent != null) {  //bug here
>             value = bodyContent.getString();
>             type = "string";
>         }
>         return (SKIP_BODY);
>     }
> The value of this tag is only being updated if there is not already a value set. So, when this tag is used twice in succession on a page, it will always only use the first "value" ever set!!!
> I looked back at the older Tiles 2.0.6 version we were using and the code is correct in that version - there is no "value == null" check. So, it looks as though someone added this little check at some point in the 2.1 release, but it seems to severely break things (at least for me!)
> I see two ways of fixing this - 
> 1.) Simply remove the value == null check, or if this check is in place for a reason,
> 2.) Reset value to null after each execution of the tag in doEndTag, or doFinally() from the TryCatchFinally interface:
