> I have source table (in PostgreSQL) with column of type *bytea*. That table/column is in source model (in Teiid) defined as *blob*. Further, I have one view which casts this column to type *object* (column name is _val_). In order to be able to insert in such view, I have defined INSTEAD OF TRIGGER (see \[2\]).
> Now I try to insert values into view \[1\]. If val is defined in insert statement, everything is OK. However, if val is not defined, insert ends with exception \[3\].

> insert into a (id) values (1)
