Cannot modify a read-only dataset ContactsDB

[beto]

The HostSync send me it message:

ContactsmQuery: Cannot modify a read-only dataset ContactsDB

Looking in sources i found that it is in this part:

unit pfgPalmSyncComponent;
...
function TpfgPalmSyncComponent.SyncFast:
...
      LocalDataSet.Open;
//
      pfgPalmRemoteTable.First;
      while not pfgPalmRemoteTable.eof do
      begin
        SyncYieldCycles(1);
        if FOnFindLocalRecordID(self, pfgPalmRemoteTable.Fields.RecordID) then
        begin
          compare_and_act(0);
          ShowMessage('compar y actu');
          pfgPalmRemoteTable.next;
        end
        else
        begin
          if not isdeleted(pfgPalmRemoteTable.fields.Flags) then
          begin
            LocalDataSet.Append;  // HERE

I dont understand, try a Append in LOCAL TABLE and the error message is in REMOTE TABLE (ContactsDB), beside the respective property in the component pfgPalmRemoteTable1 is ReadOnly : False, and the atributte in the PALM table is not checked in ReadOnly

Can you help me please?

(my english is poor, excuse me please)

I'd suspect at a guess the problem is that you're using a query component, with the synchronisation component set to bi-directional synchronisation. By default, queries don't allow their contents to be modified, so when it tries to append a record to the local dataset, the query component throws an error.

You have two options. Firstly, query components can be set to allow updates. Or, you may be able to set the synchronisation component to only do uni-directional synchronisation. I'm not sure the exact details in either case, but hopefully it'll give you enough to fix your error.
