I've just upgraded to 3.2.2 from 3.0.04 and I've noticed a change in the way that items are chosen for the autocomplete pop-up (I believe that's what SQL Developer calls "Completion Insight").
In earlier versions, while typing a query like this:
FROM ORDER ORD
INNER JOIN CUSTOMER CUS ON ORD.
... I would get column names from the ORDER table and nothing else. In 3.2.2 I get a large list with columns from both tables in what appears to be alphabetical order, so I need to scroll down the list just to see columns from ORDER. And it's even worse when there're more tables involved.
Is it a known issue? Is it a configurable behaviour?
