Hello Nerissa,
It would appear that oUserMgr doesn't have an instantiated data environment at runtime.

I would suggest adding

SET STEP ON
RETURN DODEFAULT()

in oUserMgr's CreateDataEnvironment(), and stepping through it to see what's happening.

I debug the program (starting at the click() of the OK button in the login form) and I found that the getalias() of this bizobj returns an empty value. Therefore, loDataAccess = This.GetDataAccessObject(tcAlias) code doesn't make loDataAccess an object. So in the code that follows,
>IF lnRetVal = REQUERY_SUCCESS AND ;
> This.lCascadeMessages AND tlDoNotRequeryChildren = .F.
