How to display form:error in another frame

[geek.shrek]

Hi,

I have my form like below


<form:form commandName="test_command" method="post" action="test.htm" name="searchForm" id="searchForm" target="main">

<form:errors path="*"/>

</form:form>

How can I have my form:error display in another frame, eg. frame2 instead in target "main"? :confused:

Thanks
