Lazarus 0.9.22 (fpc 2.0.4), PostgreSQL 8.2., Windows XP.
When I try to code any event of ZTable component, I get the following
error:
"C:\lazarus\components\ZEOSDBO-6.6.1-
beta\src\component\ZDataset.pas(54,6) Error: identifier not found:
TDataSetNotifyEvent"
So, I can't assign any event to ZTable!

Regards,

Zlatko

Chris, thank you for your reply.
Unfortunately, I don't understand French, so I'm not sure that I
understood guidance from your web site.
I added "Db" and "Classes" in USES of Zdataset.pas, in the following
folder: C:\lazarus\components\ZEOSDBO-6.6.1-beta\src\component.
But, now I have an error when trying to compile:
"C:\lazarus\components\ZEOSDBO-6.6.1-
beta\packages\lazarus\zcomponent.pas(11,18) Fatal: Can't find unit
ZDataset".

The Zdataset. pas now looks like this:

{                                 Zeos Development Group. }
{********************************************************@}

unit ZDataset;

interface

{$I ZComponent.inc}

uses ZAbstractRODataset, ZAbstractDataset, ZAbstractTable, Db,
Classes;

type

  {** Implements an universal SQL query for read/only data access. }
  TZReadOnlyQuery = class (TZAbstractRODataSet)
  published
    property Active;
  {$IFDEF VER130BELOW}
    property IsUniDirectional;
  {$ENDIF}
    property SQL;
    property ParamCheck;
    property Params;
    property Properties;
    property DataSource;
    property MasterFields;
    property MasterSource;
    property LinkedFields; {renamed by bangfauzan}
    property IndexFieldNames; {bangfauzan addition}
    property Options;
  end;

  {** Implements an universal SQL query for read/write data access. }
  TZQuery = class (TZAbstractDataSet)
  published
    property Active;
    property ReadOnly default False;
    property SQL;
    property ParamCheck;
    property Params;
    property ShowRecordTypes;
    property Properties;
    property DataSource;
    property MasterFields;
    property MasterSource;
    property LinkedFields; {renamed by bangfauzan}
    property IndexFieldNames; {bangfauzan addition}
    property Upda]"]>Blockedde;
    property WhereMode;
    property Options;
    property Sequence;
    property SequenceField;
  end;

  {** Implements an universal SQL query for single table access. }
  TZTable = class (TZAbstractTable)
  published
    property Active;
    property ReadOnly default False;
    property TableName;
    property ShowRecordTypes;
    property Properties;
    property MasterFields;
    property MasterSource;
    property LinkedFields; {renamed by bangfauzan}
    property IndexFieldNames; {bangfauzan addition}
    property Upda]"]>Blockedde;
    property WhereMode;
    property Options;
    property Sequence;
    property SequenceField;
  end;

implementation

end.

What's wrong?
Is the problem in paths?
How to fix it?

Thanks in advance,

Zlatko

Hi, again!
It seems that "Clean recompile" helped. Now it works.
Thank you very much, Chris!

Regards,

Zlatko

P.S. Have you reported this issue to ZEOSlib developer team? I think
they should know it before next official Zeos release.
