TRtcMemDataset problems

[Max Terentiev]

Hi,

I notice some problems with TRtcMemDataSet:

1. First() method not working (not move table cursor to first record)
2. DevExpress's DBTreeList.SyncMode not working with TRtcMemDataSet (changing node in TreeList not change cursor position in TRtcMemDataSet). But it's working with any other DataSets including TRtcClientDataset.

I fill data to TRtcMemDataSet (GroupsTbl) this way:

void __fastcall TListManagerFrm::GetGroupsReturn(TRtcConnection *Sender, TRtcValue *Data,
     TRtcValue *Result)
{
if(Result->isType==rtc_DataSet)
   {
   ClientDM->GroupsTbl->Close();
   ClientDM->GroupsTbl->asObject=Result->asDataSet;
   Result->Extract();
   ClientDM->GroupsTbl->Open();
   }
}
//---------------------------------------------------------------------------

Received data showed in DB controls with no problems.
But if I call GroupsTbl->First() - it's not move table cursor to first record, it's just does nothing.

Update: problem happens only if TRtcMemDataSet used with DevExpress TcxDBTreeList. With TDBGrid all works fine including First() method.

But it's probably bug anyway because TcxDBTreeList works fine with any another DataSets including TRtcClientDataset !

TRtcMemDataSet component is outdated and kept ONLY for legacy reasons (OLD Projects which have to be compile with FreePascal). If you are using Delphi to compile your Projects, please switch to the TRtcClientDataSet component, which extends the TClientDataSet component from Delphi with a TRtcDataSetMonitor component from RTC.
