To jiwasz: one way this can be done is by using code. There’s a Validating event available for all group nodes; in the event handler, you can check for some condition and add an item to the Errors collection, if necessary.
Another option is custom-designing an XSD schema, and then starting an InfoPath form template from that XSD. InfoPath will respect your schema restrictions.
Any idea why I would be getting this error when publishing to MOSS:
The SOAP response indicates that an error occurred on the server:
Server was unable to process request. ---> Object reference not set to an instance of an object.
-I've followed all of MS' implementation steps for this control.
I'm sorry, I'm quite new to InfoPath development, but I believe this is exactly what I'm looking for and I don't really understand how to do it. I see how to add a custom activex control, but it just gives me a huge list of controls and I have no idea which one to choose. I'm sorry if I'm missing something above, but I do not see it.
This is an InfoPath 2007 control and should be listed in the ActiveX controls as "Contact Selector."
