Description
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
insert into a (id) values (1)
