Adam Greenfield created WW-4701:
-----------------------------------

             Summary: Can no longer clear parameter on a <s:url> tag.
                 Key: WW-4701
                 URL: https://issues.apache.org/jira/browse/WW-4701
             Project: Struts 2
          Issue Type: Bug
    Affects Versions: 2.5.5
            Reporter: Adam Greenfield


Consider the following:

{noformat}
<s:url action=“init” includeParams=“get”>
    <s:param name="param1" value="" />
</s:url>
{noformat}

Before 2.5.5, this would have removed “param1” from the generated url if it was present.
 (The evaluated value would have been null, and so Component.addParameter(name, value) would
have removed the parameter).
