Greg Lindholm created WW-4631:
---------------------------------
Summary: Empty <s:param name="p1" value=""/> is being supressed
Key: WW-4631
URL: https://issues.apache.org/jira/browse/WW-4631
Project: Struts 2
Issue Type: Bug
Components: Plugin - Tags
Affects Versions: 2.3.28
Reporter: Greg Lindholm
Priority: Minor
I discovered a problem with the <s:param /> tag when attempting to pass an
empty parameter.
<s:url var="myUrl" action='MyAction'>
<s:param name="p1" value=""/>
<s:param name="p2"></s:param>
</s:url>
I was attempting to pass an empty parameter using the "p1" syntax above and the
parameter was being suppressed.
Using the "p2" syntax it works correctly, and the empty parameter is included.
The doc http://struts.apache.org/docs/param.html says that
"suppressEmptyParameters" defaults to false but the p1 parameter was always
suppressed even if I added suppressEmptyParameters="false".
Also the doc http://struts.apache.org/docs/param.html has an incorrect example
on how to use the suppressEmptyParameters option.
<s:param name="suppressEmptyParameters" value="true"/>
