Dynamic forms and Web Services?

Question

So what we are trying to do is get a dynamic form's information into a database.  On the form itself we have several fields wrapped in a subform that is set to repeat.  It is bound to an element from a web service, which allows the form to grow based on the number of rows returned.  We needed to do this because depending on the selection of departments, there could be a different number of rows returned each time.  This works out fine.  The form grows to display different options, based on the selection.
What we're having problems with is writing the changes made back to the database.  We have a web service that is bound to the subform that contains the fields, and also bound to the fields themselves, but we're only able to write the information from the last node, i.e if there were six options that were displayed, and you made changes to all six, only the changes to the last one would be written to the database.  Is there something special that needs to be done on the form side?
Any help is much appreciated.

Answer 1

Yes ...you set up the web service to recieve one parameter .....then you create a multiline field (make it invisible so the user cannot see it). Then use this command to populate the field with the form data:
fieldname.rawValue = xfa.datasets.data.saveXML("pretty");
Now bind this field to the web service input and call it.
