Hi all!
I'm designing a webservice in Webratio, in wich one request arrives to service with an coordinates window, and the service has to return all information between these coordinates.

When the web service is requested, and there is only one row at coordinates window, it functions perfectly.
And here is my problem, when at the coordinates window there are more than one row, XMLOut unit selects the proper data from database, but the RequestRespondUnit goes into error, and the ErrorResponseUnit gives me the following error: "Double ID".
¿Someone knows what are i'm doing wrong or what have i to do for it works fine?
Thanks
