Spring mvc: Controller Result resent to RequestMappingHandlerMapping - spring-mvc

Question

I have an abstract Spring Controller class extended by various controllers.
Example method:
#Override
#RequestMapping(value = { "/", "" }, method = RequestMethod.GET)
public String getAllAsView(#RequestParam(required = false) boolean ajax,
Model m) {
String mapping = elementClass.getSimpleName();
m.addAttribute(mapping + "List", getAll());
return mapping + "All" + (ajax ? "Ajax" : "");
}
These are the relevant definitions in my view.xml:
<definition name="maintemplate" template="/WEB-INF/views/main_template.jsp">
<put-attribute name="top" value="/WEB-INF/views/header.jsp" />
<put-attribute name="side" value="/WEB-INF/views/menu.jsp" />
</definition>
<definition name="ajaxtemplate" template="/WEB-INF/views/ajax_template.jsp">
<put-attribute name="top" value="/WEB-INF/views/header.jsp" />
</definition>
<definition name="PersonAll" extends="maintemplate">
<put-attribute name="content" value="/WEB-INF/views/personlist.jsp" />
</definition>
<definition name="PersonAllAjax" template="ajaxtemplate">
<put-attribute name="content" value="/WEB-INF/views/personlist.jsp" />
</definition>
With the ajax parameter only the body content is to return.
Everything works fine without the ajax parameter.
But with the Ajax parameter the return string is used for a new Controller request.
This is the Log:
DEBUG: org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping - Looking up handler method for path /person/6

</bean>
I am stuck finding out what is happening here. I changed the template name and the new name was used for the request.
The problem came up, after I changed nearly all xml files in project. I inserted Doctype tag and changed schema definitions and stuff. Because that caused heavy problems I stepped back to a working version. Before that, the ajax parameter worked.
Ah - and I updated to java-version 1.6.
Any ideas why spring uses the templatename "ajaxtemplate" as a new request and sends it back to the controller?
Best regards

Stupid mistake: never programm past midnight:
<definition name="PersonAllAjax" template="ajaxtemplate">
<put-attribute name="content" value="/WEB-INF/views/personlist.jsp" />
</definition>
must be
<definition name="PersonAllAjax" extends="ajaxtemplate">
<put-attribute name="content" value="/WEB-INF/views/personlist.jsp" />
</definition>
