Messaging Plugin Exception with Delphi XE2 and NexusDB 3.10

In the following Routine in the line aList.LoadFromStream, I get the
exception Invalid Propertievalue since I'm using Delphi XE 2 and NexusDB
3.10. Any ideas?

Best wishes
Bernhard

function TpsnxRemoteMessagingPlugin.GetMessagingClients(aLi st:
TpsnxRegisteredClientList)
: TnxResult;
var
MStream: TStream;
begin
MStream := TnxMemoryStream.Create;
try
Result := bpeProcessRequest(nxnmGetMsgSessions, nil, 0,
@Pointer(MStream), nil, nmdStream);

if Result = DBIERR_NONE then
begin
MStream.Seek(0, soFromBeginning);
aList.LoadFromStream(MStream);
end;

finally
MStream.Free;
end;
end;

Same story here
Using NexusDB 3.10.04 with Delphi 2007.

Also get the "Invalid PropertyValue" error in the routine "LoadFromStream"

procedure TpsnxRegisteredClientList.LoadFromStream(aStream: TStream);
var
...
begin
  Reader := TReader.Create(aStream, 4096);
  try
    aCount := Reader.ReadInteger;

    for Index := 0 to (aCount - 1) do
    begin
      SessionID       := Reader.ReadInteger; <-- Error starts here
      ...
      ...
    end;
  finally
    Reader.Free;
  end;
end;

Hi,

Try changing the designated row to

SessionID := Reader.ReadInt64;

That is the way it is in my code here, and I vaguely remember having
changed it in code I uploaded. Can't see that now, but I guess it is the
way it should be....

Search the support group for ReadInt64. There is a discussion dating
back to 2010.
Currently I am still using version 3.05, so I don't know which changes
to the code were made since then.
Can you confirm that the problem only occurs on systems with a 64-bit
OS?

Bert,

I wasn't speaking about the nexusdb code - the messaging plugin lives
it's own life as a third party add-on. I made some changes to the
project, and it was that code I was referring to: I thought the change
should be there. The problem existed on my non-64-bit machines as well,
so - no - it has nothing to do with you OS.

Sorry, Bert,

I thought the change was something I had done at the time, but I now
found your discussion in support from August 2010. I rest my case :-)
