Hi,

  Recyclable jForm Create and Init sequence has changed and broken my
App. I don't know when this change happened but with the latest
LAMW from GIT my application crashes. It was working perfectly. I have
tried all sorts of ways to get my App to not crash and no luck.

  How am I meant to Create and Init Recyclable jForms in LAMW App?

  I create Recyclable jForms as below:

procedure EditStockTakeItems(  pCallingForm : jForm; poDocument :
TDocumentTransferObj; pOnCloseCallback : TNotifyEvent );
begin
  if frmStockTakeItems = nil then
    begin
      gApp.CreateForm(TfrmStockTakeItems, frmStockTakeItems);
      frmStockTakeItems.pCallingForm := pCallingForm;
      frmStockTakeItems.poDocument := poDocument;
      frmStockTakeItems.Init(gApp);
    end
  else
    begin
      frmStockTakeItems.pCallingForm := pCallingForm;
      frmStockTakeItems.poDocument := poDocument;
      frmStockTakeItems.Show;
    end;
  frmStockTakeItems.SetCloseCallBack(pOnCloseCallback, pCallingForm );
end;

hi,
look AppDemo1 in demos\GUI or move createform / init code in
OnActivityCreate method
