JS client: Combo box keypress events: FIXED

[Das Goravani]

This is a fast and slick pop up list generator. 
You use a regular field and a regular list
The hard part, is getting the characters they type correctly, this does it.
I use this to show a list of countries as they type it populates.


On evKey
  Hide fields NoteFieldLarge,CitiesList
  Do $topwind.$objs.BDEntryPane.$bobjs.1457.$visible.$assign(kFalse)
  Show fields CountriesList

  Process event and continue
  Calculate ltypedstring as $cfield.$contents
  Calculate cWhereClause as con('WHERE cntry_name LIKE "',ltypedstring,'%"')
  Do tvO.$buildlistfromfileusesearch(ivCountriesList,'fcCountries',cWhereClause)
  Redraw CountriesList

And I do the following when they double click in the list of countries

On evClick
Set current list ivCountriesList
Calculate #LSEL as 1
Calculate #S1 as lst(ivCountriesList,#L,cntry_name)
If len(#S1)
Do $topwind.$objs.BDEntryPane.$objs.BIRTHCOUNTRY.$contents.$assign(ivCountriesList.cntry_name)
Calculate iv1.birthcountry as #S1
Redraw (Refresh now) BIRTHCOUNTRY
Queue set current field BIRTH_STATE
Calculate lwhere as con('WHERE state_country = "',ivCountriesList.cntry_name,'"')
Do tvO.$buildlistfromfileusesearch(iStatesList,'fcStates',lwhere)
Redraw StatesDrpLst
End If

This would appear to be an ideal candidate for a combo box, however that control doesn't have keypress events so you are constrained to waiting for the user to leave the field?
