InfoPath Dev

Hi, i followed Itaysk’s intructions to use the GetUserProfileByName and managed to retrieved the logged in user’s first and last name ok. However it only works in InfoPath 2010 with Preview. After i’ve published it in SharePoint 2010 and test the form, the fields are blank. My colleague here has a similar form with the same fields – First and Last name. it works fine for his form in SharePoint2010. This is what we both have for the First Name field “xdXDocument:GetDOM(“GetUserProfileByName”)/dfs:myFields/dfs:dataFields/tns:GetUserProfileByNameResponse/tns:GetUserProfileByNameResult/tns:PropertyData[tns:Name = "FirstName"]/tns:Values/tns:ValueData/tns:Value”. Just can’t understand why his published form works in SharePoint 2010 and mine doesn’t. We both publish to the same server – site.
Your comments would be much appreciated.

Check if the server is throwing a 5566 error, in which case you may find the permissions (either the site or of the user profile service ) are not allowing it.

I was having a similar problem then I changed my datasource to be a subsite URL, so instead of 

http://intranet/_vti_bin/UserProfileService.asmx?WSDL

it was

http://intranet/IT/_vti_bin/UserProfileService.asmx?WSDL

last resort; under central admin , service applications, add yourself to administrators and permissions for the User Profile Service Application and try again
