Focus hijacked - possibly by patch code?

[trjackson77]

I am having trouble with a gallery for the input of data.  It has three text input controls (txtCount1-3).  I want the focus to move from txtCount1 to txtCount2 (and 2-3) when data is entered.  There is some code running onChange that patches a collection.

When entering data I can see that the focus moves from txtCount1 to txtCount2, but then almost instantaneously moves back to txtCount1.  What is going on?

how does that focus move from txtCount1 to txtCount2? By pressing TAB on the keyboard?

If yes, patching OnChange into the same collection as gallery's data source collection will reset tabbing order.

Patching to a different collection will not reset that tabbing.
