Forms 10.3

We noticed that when you have more than one lookup criteria and have the "Show Auto Fill button" option unchecked, lookups don't trigger the onchange event on target fields.

To reproduce:

1. Have Field1 as first criteria
2. Have Field2 as second criteria, and configure a default value (not sure if the default value is necessary)
3. Have Field3 populated via lookup based on Field1 and Field2
4. Have an onchange event handler for Field3

The event never triggers when Field3 is populated. But it works if the Auto Fill button is shown.
