Lukasz Lenart updated WW-4312:
------------------------------
    Description: 
I can't explain well so see below.

Expected "1, 2, , 3," but the result was "1, 2, 2, 3,".

Test.jsp
{code:xml}
<s:iterator value="%{{{1, 2},{null, 3}}}" var="var1">
<s:iterator value="#var1" var="var2">
<s:property value="#var2" />,
</s:iterator>
</s:iterator>
{code}

I changed below class then it was fixed.

org.apache.struts2.components.IteratorComponent#start
{code:java}
//  if ((var != null) && (currentValue != null)) { <= Old.
    if (var != null) { // <= New.
        //pageContext.setAttribute(id, currentValue);
        //pageContext.setAttribute(id, currentValue, PageContext.REQUEST_SCOPE);
        putInContext(currentValue);
    }
{code}
