0 (zero) is not a valid timestamp

edited April 2011 in General
Hi all,

Delphi XE, EB 12.03

When I doubleclick on my tppReport Icon I get the error message "0 (zero) is
not a valid timestamp".
I click OK and doubleclick on the report again, and the report opens in
designer completely blank.

I close the report, and doubleclick again, and the report opens in the
designer OK.

Now all the reports works just fine in the designer, until I restart Delphi
XE. The first report I doubleclick on after restart gives me the error
message again.

Do anybody know how can I get rid of this error message?

    Hi John,

    I first suggest upgrading to RB 12.04. Does this happen when opening
    any report? If you create a simple new application, place a TppReport
    on a form and double click it do you still get the error?

    What type of database and connectivity are you using? Any more
    information on your application would be helpful.

    Ni Nico,

    I have upgraded to RB 12.04, still same problem.

    The problem happen no matter which report i open first, but it only
    happens once pr. time I open the project.

    If I create a new application and add a TppReport, I don't have the

    I am using NexusDB 3.08 database. If I add a new TppReport and
    TppDBPipeline to my existing project, set the datasource and
    doubleclick on the report I get the error message.

    Error report below:

    0 (zero) is not a avalid timestamp.

    According to the call stack the issue occurs in NexusDB.

    The last RB code to execute is TppDBPipeline.GetFieldNames. Start at that
    call and read up.

    TppDBPipeline.GetFieldNames calls TDataSet.GetFieldNames, which calls some
    other TDataSet methods and then eventually Nexus classes are called. The
    last call is Nxsdnativevariantconverter.VariantToNative.

    From the name of the last method, my guess is that you have 0 stored in the
    database and Nexus tries to convert the 0 to a timestamp and raises an

    Try creating a test that uses NexusDB but not RB. Create a new application,
    place the NexusDB components on the form and connect a DBGrid. Open the

    I added a TppReport and TppDBPipeline to the same dataset, and no
    errors here either.

    Can the problem I see here have anyting to do with Delphi XE compared
    to Delphi 7 from which I upgraded my Project?

    I went from Delphi 7 to XE at the same time as I upgraded to RB 12.03
    and Nexus 3.08.

    I recommend posting this question to NexusDB. From reading the call stack,
    that is where I would focus. Perhaps you moved to a different version of
    NexusDB or perhaps they have a different code base for Delphi XE. It is
    interesting that creating a new dataset does not cause the issue, I would be
    sure to mention that to them and to show them the call stack. Perhaps they
    have heard of this error before.
