The code does not produce an exception or a crash... - but it does return wrong values.
I will return nulled values - but there are real values - as I have seen when I do directly use the registration structure instead of the union. It does look like it does not get initialized...
Regards, Wolfgang

Once you've called "read", you can simply access the corresponding union field. getTypedValue is a shortcut for setType + read. How exactly does this code fail?
