> Hello,
> When using the s:a anchor tag you can get parameters with empty values ie ?foo= for null values. 
> It would be good if there was a way to filter these out, similar to the struts.xml <param name="suppressEmptyParameters">true</param>. The <s:if> tags in the body are ignored.  I either have to do it in programatically or use jstl :(
> ie possibly do something similar :
> from:
> {code:xml}
> <s:a action="eventAdd" accesskey="a">
> <s:text name="title.heading.eventadd" />
> <c:if test="${not empty bean.searchString}">
>  <s:param name="bean.searchString" value="%{bean.searchString}" />
> </c:if>
> <c:if test="${not empty bean.filter}">
>  <s:param name="bean.filter" value="%{bean.filter}" />
> </c:if>
> <s:param name="bean.pageNum" value="%{pager.pageNumber}" />
> </s:a>
> {code}
> To:
> {code:xml}
> <s:a action="eventAdd" accesskey="a">
> <s:text name="title.heading.eventadd" />
> <s:param name="bean.searchString" value="%{bean.searchString}" />
> <s:param name="bean.filter" value="%{bean.filter}" />
> <s:param name="bean.pageNum" value="%{pager.pageNumber}" />
> <s:param name="suppressEmptyParameters" value="true"/>
> </s:a>
> {code}
