Hi Jason,
i have installed your 4.2Ga and i have try your Resync([]) solution.
For "ditInsert" and "ditDelete" case all seem to work fine but "ditEdit"
case have some refresh problem.

I attach here my C++ code, how you can see in "ditEdit" case i do only an
InvalidateBookmark() but when i do this my current record are changed and
the Grid display another section of the table (??).

void __fastcall TIsIBOTable::DefaultDMLCacheReceivedItem(TIB_Dataset
*ADataset, const TIB_DMLCacheItem *ADMLCacheItem)
{
//
// From: IBA_BDataset.IMP -->
TIB_BDataset.DefaultDMLCacheReceivedItem()
//

TIBOInternalDataset * IDataset = dynamic_cast<TIBOInternalDataset
*>(ADataset);

if ( IDataset )
{
int ii;
String tmpStr;

tmpStr = "";
for (ii = 0; ii <= IDataset->KeyFields->ColumnCount - 1; ii++ )
{
if ( ii > 0 )
tmpStr = tmpStr + ";";

tmpStr = tmpStr + IDataset->KeyFields->Columns[ii]->FieldName;
}

if ( AnsiCompareText(ADMLCacheItem->KeyFieldNames, tmpStr) == 0 )
{
IDataset->KeyFields->Values[ ADMLCacheItem->KeyFieldNames ] =
ADMLCacheItem->KeyFieldValues;

if ( State == dsEdit || State == dsInsert )
FFlagDMLRefreshPending = true;

if ( State == dsBrowse )
{
FFlagDMLRefreshPending = false;

TResyncMode syncMode;
syncMode.Clear();

switch ( ADMLCacheItem->DMLCacheItemType )
{
case ditEdit:
InvalidateBookmark(IDataset->KeyFields->RowData);
break;

case ditDelete:
{

IDataset->DeleteBufferBookmark(IDataset->KeyFields->RowData );
UpdateCursorPos();
Resync( syncMode );
}
break;

case ditInsert:
{
IDataset->InsertBufferBookmark(
IDataset->KeyFields->RowData );
UpdateCursorPos();
Resync( syncMode );
}
break;
}
}
}
}
}
//--------------------------------------------------------------------------

Enrico Raviglione.

buffer syncronization


Use the Resync([]) method to get it to resynchronize the tdataset bufferes
with the internal dataset buggers.
