Exception raised when trying to start report explorer

edited April 2002 in General
Hi.

I have RB pro (eval) downloaded, and am using it with Delphi 6 pro.

I am trying to do something like the end-user reporting demo.

I have set up an access 2000 database with the folder and item tables and
fields (no items added, just the tables and field definitions), and an ADO
connection to this access database. This in turn is
hooked up to ADOTables which are hooked up to the DBPipileines. There is a
designer, explorer, and report and the table/datasource/pipeline for the
folders and the items, hooked up to the explorer. The databasename in the
designer's datasettings is set to a different ADOConnection than the one for
the folders and items, which has the
data I want in that database. Databasetype is set to Access, SQL2. I
included

When I start it up and click the launch button, (which has only the code
ppReportExplorer1.Execute;) I get

" Project [whatever.exe] raised exception class EVariant with message
'invalid type conversion'. Process stopped [etc]"

What is the problem? I can't see that I've done anything non-standard and it
all should work.

Thanks,

Lauchlan Mackinnon.
