> h3. Phenomenon
> 1. Submitting form with parameters using URL contains querystring consisted of some fields.
> {noformat}
> <s:form id="testForm" action="Test.action?field1=%{field1}&field2=%{field2}">
> {noformat}
> Field1, field2 are member of Test class.
> Each setter is implemented in this class.
> \\
> 2. When form tag in struts is interpreted as in HTML, "action" atrribute is this.
> {noformat}
> action="Test.action?field1=value1&amp;amp;field2=value2"
> {noformat}
> Due to duplication of "amp;", it causes field2 member to fail to recieve value.
> therefore, field2 member equals NULL always.
>  
> \\
> Desired result 2. is this.
> {noformat}
> action="Test.action?field1=value1&amp;field2=value2"
> {noformat}
> \\
> h3. Cause
> Character entity reference about "&" is executed twice.
> Executed points are as follow.
> --------------------------------------------------------------------------------
> ・/core/src/main/java/org/apache/struts2/views/util/DefaultUrlHelper.java
> {noformat}
> String buildUrl(
>  String action, HttpServletRequest request, HttpServletResponse response, 
>  Map<String, Object> params, String scheme, boolean includeContext,
>  boolean encodeResult, boolean forceAddSchemeHostAndPort, boolean escapeAmp
> )
> {noformat}
> ・/core/src/main/resources/template/simple/form-common.ftl
> {noformat}
> <#if parameters.action??>
>   action="${parameters.action?html}"<#rt/>
> </#if>
> {noformat}
> --------------------------------------------------------------------------------
> h3. Solution
> "escapeAmp" in method "DefaultUrlHelper.buildUrl" is set false. 
> My patch file is attached.
