#2 TDataSet: Error in filter

[Anonymous]

TDataSet:
When a record is filtered, and it's working in read
only mode when the record goes from the dbg (dbgrid)
to S (select) action, the filtes goes well, but when i
hit the List button, then the filter is corrupted.
There should be a fail in the listbutton_params
variable when returns from S to DBG in a readonly mode.
