Lukasz Racon commented on WW-2435:
----------------------------------
My fault, it should have been return TRUE, return false doesn't change
anything. Code wasn't used in production since it was easier to use c:set
instead of creating another build from the trunk.
Based on
http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/servlet/jsp/tagext/BodyTag.html:
doStartTag() should return EVAL_BODY_BUFFERED, so BodyContent object is created
(by JSP compiler) and set on a tag.
If BodyContent is not set on a tag the StrutsBodyTagSupport.getBody returns
empty string. In this case Set.end method would use the "top" value from OGNL
stack.
> <s:set> tag does not evaluate Body
