Database Adapter using Logical Delete Polling Strategy not updating field

Question

I have an ESB database adapter defined against a table. The adapter is set to use the Logical Delete Polling Strategy, and the table has an extra column defined as the "delete" field. When I register the adapter to the ESB and add a record to the table, the adapter reads the contents of the record as expected. However, 15 seconds later (that being the polling interval) it reads it again, and again 15 seconds after that, ad infinitum.
I have defined the logical delete field as a single character field and set the Read value for "T" (a record is normally inserted with that field having a null value). Results as outlined in the previous paragraph. I redefined the field as a number and set the Read value to "1" (with a record normally inserted with that field having a value of "0"). Results as outlined in the previous paragraph.
Apparently the update of the logical delete value to the Read value is not occurring. My question (obviously) is: Why?
Thanks for your time.

Here is the adapter WSDL:

The field PROCESSED is defined as CHAR(1), and is normally null when a record is inserted. The value of the field is to be set to 'T' when the record is read by the polling adapter.
