It appears that if a CSV file has blank lines at the end of it the ADK method "Import" places a record into the database. For example with this CSV file:
"fldID","fldName"
1,"Sig_1_30"
2,"Sig_2_30"
3,"Sig_3_30"
<- blank line
<-
I get the following into my table:
fldID fldName
1 Sig_1_30
2 Sig_2_30
3 Sig_3_30
