UniQuery error: Cannot modify a read-only dataset!

[soyjoy]

Hi,
I am using a UniQuery to execute select commands, insert, delete and update, but when I delete a record, returns the error: Can not modify a read-only dataset. Even after you have generated SQL statements with SQL generator. What can it be? My setup is TUniConnection> TUniquery> TUniTransaction. Grateful now.

Unfortunately, we can't reproduce the issue. To investigate this behavior of UniDAC, please send to viktorv*devart*com a small sample to demonstrate the issue, including a script for creation and filling in the test database object.
