Description

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:

<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>

To:

<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>
