Collection is populated, but HALF of the total records have null values?

Question

can anyone see why this may not be working properly. I am creating a collection (CATCH_C) based on the number of rows in an existing collection (EFFORT_C). For every record in EFFORT_C, there needs to be one in CATCH_C.
In my example, I know that there are two EFFORT_C records. There are 12 records in the table FREQUENT_SPECIES, therefore, my CATCH_C collection should (after running through loop) have 24 records.
CATCH_C is created with 24 records, however record numbers 16-24 only have the data for disposition_code. The other data is all missing...however rows 1-15 are perfect. Any thoughts?
thanks! Karen

Answer 1

I thought I had resolved as it seems driven by pagination....but alas (while pagination is odd), the disposition code still appears for every collection record...but the other data does not. again, any thoughts are appreciated.
