>                 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
>             Fix For: 2.5.6
>
>
> 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).
