Error when I execute an action using links

Hi Friends,

Problem
Getting into an endless loop when I am clicking on a edit link which leads me to an edit Page.

Struts 2, Tiles

JSP Code
 

<s:iterator value="list" status="listStatus">
<s:url id="editURL" action="EditAction">
<s:param name="type" value="%{type}"></s:param>
</s:url>
<s:a href="%{editURL}">Edit</s:a>
</s:iterator>

Select allOpen in new window

Tiles
 

<definition name="Page1" extends="baseLayout">
      <put-attribute name="title"  value="Page1"/>
      <put-attribute name="body"   value="/Page1.jsp"/>      
</definition>

Select allOpen in new window

Struts
 

<action name="EditAction" method="EditAction" class="grouping.master.action.Action">
<result  name="success" type="tiles">Page1</result>
</action>

Select allOpen in new window

The error what I am getting
