why change or task state got by web service doesn´t match current state in hpsm?

Hi All,

 

I have a problem invoking change webservice using RetrieveChangeListRequest. or  As far as I see, the state got invoking this web service doesn´t match current state in hpsm.

This is my requests:

var xml3 = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:ns=\"http://schemas.hp.com/SM/7\" "
"xmlns:com=\"http://schemas.hp.com/SM/7/Common\" xmlns:xm=\"http://www.w3.org/2005/05/xmlmime\"> <soapenv:Header/>"
"<soapenv:Body> <ns:RetrieveChangeListRequest attachmentData=\"false\" attachmentInfo=\"false\" ignoreEmptyElements=\"true\">"
"<ns:model><ns:keys query='((AssignmentGroup=&quot;mygroup&quot;) and (Status=&quot;Open&quot; or Status=&quot;Work in Progress&quot; or Status=&quot;Pending Customer&quot; or Status=&quot;Pending Vendor&quot;) )'/></ns:model> <ns:instance />"
"</ns:RetrieveChangeListRequest></soapenv:Body></soapenv:Envelope>";

Thanks a lot!
