inputField focus issue in ECC 6.0

We are upgrading from 4.7 to ECC 6 - I have a BSP app which is behaving differently in ECC 6. When tabbing between inputFields within an iterator, the first tab will place the cursor focus around the inputField, then the second tab will place the focus inside the inputField. You cannot start typing into the inputField until the 2nd tab. This is very annoying and confusing to the user. Is there anyway to change this behavior so that the cursor focus moves inside the field on the first tab? This does not seem to happen with inputFields which are not within an iterator. This does not happen with 4.7. Any insight would be greatly appreciated.
