sqlite, params, insert not working

[vbazovic]

Enviroment: CodeTyphon 4.9 with Zeos Rev 3112, ver 7.2.0 has a problem (works fine with 7.1.2) with sqlite3 (3.7.16.1 library version) on Linux.

When you try an insert/update query with parameters (ParamByName method) it does not work. This is some debug info:

Exception class: EZSQLException
Message: SQL Error: constraint failed

The only constraint is primary key.

When I drop this constraint I get correct number of rows with all nulls!!! SQL was insert into table with retruning statement (used Open method ).
PK is varchar.

I did try to fix it myself but without success.

Could you attach a simple demo, please? just a console app would be sufficient..
