InfoPath Dev

Seems like a silly question, but is there a way to refresh a Web Service Connection so that it updates the available fields in the Data Sources?

I am building a Browser Enabled forms and I am pretty much complete with the "mock up".... 
But I imagine I will add a few items here or there as my customer hacks off on the concept.

I ask this question because I had a problem with my ID column showing in the WebService connection.
InfoPath would error because the ID column wanted data, but I didn't need data because is was an auto-increment manged by the SQL Server.
I finally relaized I could switch the ID column from Public to Internal in the WebService and it would be de-serialized - but it left the ID in the Data Connections.

No matter what I did, I couldn't get InfoPath to realize the ID column was no longer there.

I wound up rebuilding a whole new form, copying and pasting my fields, and then rebinding every field.

So again, if I change my webservice to add/drop a field - how can I make InfoPath "refresh" so it recognizes the changes?

I just Modify the existing and then it requeries and updates the DS.

In 2007 there was a "Convert Main Data Source" from the Tools menu (I have no idea where this went in 2010 and frankly I don't care since we use XML data sources not generated from DB or WS).

You shouldn't have to rebuild the form.

XML data sources - guess I gotta get spun up on that.

I am using a webservice because I am trying to deploy to Form Services - using IP2007....

I agree, should be able to just change the WS and see the changes reflected next time to modify the service and reconnect.
But that's not happening over here for some reason.

I remove a field from the WS, build a whole new connection - not there.
Open an exisiting form, modify data sources, next, next , next, next - the now missing field is still listed in the form.
(since the fields I was working with where Required/Primary Key - couldn't bypass them upon submit).

 Anyways....

Still open to anyone else who has seen this before.

thanks for the info!
