During development in B4J, the following error message appears in Debug mode after a Focus request. However, the app continues to function. Do I have to worry? Or can I ignore the error message?
Private Sub CustomListViewTeamNames_ItemClick (Index As Int, Value As Object)
ChosenTeam=Index+1
TextFieldGiveTname.Text=Main.sGroupeTeamName(NextGroupe,ChosenTeam)
TextFieldGiveTname.RequestFocus
'TextFieldGiveTname.RequestFocus 'gives fault (?)
End Sub
Waiting for debugger to connect...
Program started.
