EditorAutoComplete and EditorCombobox share code on function cleanup, setEditor, onPageAttached, onPageDetached
i guest by multi inherit.

for java 8 can do like before
extract code of that method to to default method of interface ITableDirEditor.
class implement ITableDirEditor just call to this default method method

Thanks for the feedback.

What you describe sounds according to the description: "Behavior is to filter the list for items that start with the letters typed when the number of letters is 1 or 2 - when the letters are 3 or more then the list is filtered for items that contains the typed."

go "Window, Tab Field"
on "Link Column" field

case1:
type "de" it show description item => OK
type "id" it isn't show "AD_Client_ID_Client" item => NG

difference by "ds" is start of string, but id isn't

case2:
type "eat" it show item "CreatedBy_Created By" => OK
use backspace to delete "t" list become empty => NG

do same with "des" it's ok ever delete "s"

i guess "case 1" and "case 2" have same reason

Integrated implementation from Elaine Tan.

It enables the flag AutoComplete on Table/TableDirect/List.

Behavior is to filter the list for items that start with the letters typed when the number of letters is 1 or 2 - when the letters are 3 or more then the list is filtered for items that contains the typed.
