Hello there
I have a table without primary key and I get an error in the mapping file. According to the documentation, the property <id> for keys is mandatory. Exists another way to map my file with any property o method?
Suggestions accepted and apprecieated.

Ok but why you give without primary key table. because it helps to fine quickly and I think this problem you faced because of it so I suggest you to give primary key to table.

First thanks for the answer roseveltein
The table had a PK. For some client requirements we had to modify the table and eliminate the PK definitely. But now face this problem with the map file.
