Forms45 interface to Crystal Reports 5.0

I'm trying to call Crystal Reports 5.0 from Oracle Forms4.5 using the ole2 built-in Packages. Has anybody successfully done this? My code just silently doesn't work and after struggling mercifully for weeks, I can't figure out what I'm doing wrong. As a test case, I'm using one of the Crystal supplied demo reports which does not require a connection string to Oracle. Basically, the following code seems like it should work:

DECLARE
lArgs OLE2.LIST_TYPE;
ActionArgs OLE2.LIST_TYPE;
hCrystal OLE2.OBJ_TYPE;
BEGIN
        hCrystal := ole2.Create_Obj('Crystal.CrystalReport');

	lArgs := Ole2.Create_ArgList;
	Ole2.Add_Arg(lArgs,'C:\temp\rpttst.rpt');
	Ole2.Invoke(hCrystal,'ReportFileName',lArgs);

	ActionArgs := Ole2.Create_ArgList;
	Ole2.Add_Arg(ActionArgs,'1');
	Ole2.Invoke(hCrystal,'Action',ActionArgs);
