Hi Ray,
I just had you set your "per" object to its constructor out of habit. Don't know about you, but I spend too much time chasing null pointer exceptions.
Try this. It's easy and quick.
1) Hold your mouse over the ObtenerPersonaActivaDadoCI() method in the Project Navigator tab. By doing this, I'm guessing you'll see it's not returning a Persona object.
or
2) Simply drag the ObtenerPersonaActivaDadoCI() method from the Project Navigator tab into your logic. By doing this, you'll notice that it has a value in front of the "=" sign. Again, I'm guessing you'll see it's not returning a Persona object.
Even though the Persona object and the object that ObtenerPersonaActivaDadoCI() returns both have the same list of attributes, I believe that you'll continue to get the error you're seeing if you try to set per (since it's an Persona object) to the value returned form ObtenerPersonaActivaDadoCI().
To get around the problem, let's say you instead have the ObtenerPersonaActivaDadoCI() method return it's value to an "opadCI" object (the type of object you found out that the method returns by doing 1 or 2 above). You might want to fix your problem by doing something like this:
per.firstAttr = opadCI.firstAttr
per.sedondAttr = opadCI.sedondAttr
per.thirdAttr = opadCI.thirdAttr
Hope this helps,
Dan
