dbExpress - "Operation not allowed on a uni-directional database"

edited September 2004 in Datapipelines

I am a Newbie evaluating Report Builder and using the evaluation version.
In working with it, I wish to use dbExpress. In doing so, I end up in a
situation where I can only display one record or if I change the Report/Data
to point to the right data-pipeline I receive an error "Operation not
allowed on a uni-directional database". It's my understanding that
dbExpress is supported by Report Builder - What am I doing wrong?

    if you are using a SQLDataset or SQLQuery you could attach them to a
    TDataProvider and a TClientDataset
    and try that

    Correct. ReportBuilder does not support Unidirectional datasets.

    If you use the Data workspace of the ReportDesigner with dbExpress, the DADE
    plug-in for dbExpress will internally create a SQLClientDataSet as part of
    the sql DataView.
