TMSTable.post problem: Operation Aborted. How to get more detailed information ?

Hello,

Using an TMSTable with 82 fields, and 1 keyfield (integer), I'm able to Insert, Delete and Edit, but when I execute Post, the operation fails with exception: Operation Aborted and no further information.

If I delete the record and then Insert, then Post will work.

With other tables with less fields, Edit-Post work fine.

How can I get more detailed information about why the operation is aborted ? Are there any logs I can set / check ?
