Re: GenericValue and nulls
this is more just my thinking out-loud However if something clicks
please chime in.
so the problem happens in an iterator.
1) I can run though this looking at one field and it goes all the way
through the list.
2) I add processing a second field and it goes through about 49 records
then has this error
a)looking at the original list creation by findlist, but not a real high
probability.
b)looking at the iterator and its storing of the list also not a high
probability.
c)looking at the String handling of the key of the record. is my guess.
possible memory allocated in processing the string.

each row has on field that is not null. did not think to
testsdenylistrcd for null. will give it a try.

The only reason I can see why you'd get an NPE on that line is if
denylistrcd were null. GenericValue won't throw an NPE on a call to
getString().

You'll have to provide more detail about the error, but
GenericEntity.getXXX(...) doesn't really throw any sort of exceptions.

is there something I missed?
