no assigned handlers for WsHeaderIn - SOAP issue from WSDL

I have a WSDL with this section:

<soap:header message=“tns:WsHeaderIn” part=“Security” use=“literal” />

webmethods keeps complaining that there are no assigned handlers for WsHeaderIn. But I’m using a security policy to generate the security header. There’s a WsHeaderIn document as input to the connector as well but I’ve been ignoring the warning. Any thoughts?

Thanks!
