Struts2: Ajax loads full pages inside target divs!!

[Raymond Holguin]

<action name="*PayrollEntry" method="{1}" class="edu.ucr.c3.rsummer.controller.manager.ManagePayrollEntry">
        	<result name="view">/manager/payroll/entry.jsp</result>
        	<result name="history">/manager/payroll/entry-history.jsp</result>
            <result name="input">/manager/payroll/entry-edit.jsp</result>
            <result type="redirectAction">viewPayrollEntry</result>
        </action>

<div id="messagesDiv" align="center">
                <s:fielderror />
                <s:actionerror />
                <s:actionmessage />
            </div>
<s:form action="savePayrollEntry">
<sx:submit cssClass="submit" targets="messagesDiv" parseContent="false" showLoadingText="true" loadingText="TESTING!!!" onmouseover="this.style.background='#F1AB00'; this.style.color='#FFF';" onmouseout="this.style.background='#e0e9f6'; this.style.color='#000';" value="Done" />
</s:form>

public String save() throws C3Exception {
		this.addActionMessage(this.getText("message.payroll.saved"));
		return SUCCESS;
	}

When i submit this button the loadingText message works fine and my action code is called, but after completion the SUCCESS is returned my "messageDiv" is filled with an entire webpage instead of the actionMessage im sending! Is there anyway i can just refresh that DIV with the message content returned from the action instead of the entire page?
