> 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
> Assignee: Lukasz Lenart
> 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).
