ppDesigner error message

rbuser

Hi guys,

I'm getting error message "EVariantTypeCasrerror: Could not convert variant
of type (NULL) into type (Integer)" when trying to save report to DB.
I use Firebird DB and got all required for end-user solution tables,
triggers and generators added to DB. Also rbItem and rbfolder pipelines and
tables configured OK.
I use Borland's TIBTable components as rbItem and rbTable dataset.

Any clues ?

With regards,
Dmitry

In addition to my previous message, some source code provided:

ppDesigner1.DataSettings.DatabaseName := Self.OrgDB.DatabaseName;
rbfolderIBTbl.Database := Self.OrgDB;
rbItemIBTbl.Database := Self.OrgDB;
rbfolderIBTbl.Transaction := Self.OrgDB.DefaultTransaction;
rbItemIBTbl.Transaction := Self.OrgDB.DefaultTransaction;
rbfolderIBTbl.Open;
rbItemIBTbl.Open;
frmReportExplorer.ppReportExplorer1.Execute;

1. If you have not done so, use the CreateEndUserTables.sql script installed
to \RBuilder\Demos\4. EndUser Databases\InterBase.

2. If you still have an error, then try the end-user examples in
\RBuilder\Demos\4. EndUser Databases\InterBase. These have been tested.

I should have added, that once you get one of the other Interbase examples
working, then try using Firebird again.

Thanks Nard,

problem was solved by changing RBFolder's and RBItems data pipelines
property RefreshAfterPost to true.
It looked like ReportExplorer could not see new records added to RB_Folder
and RB_Item tables.

Cheers,
Dmitry
