Missing drivername property - help

rbuser

I have an application updated from Rbuilder 7.04 D6 (Interbase) to Rbuilder
9.01 D7 (interbase)
When i use Report Explorer to open any report i receive de message "missing
drivername property"
If i create the report at runtime ( without reportexplorer) it works fine.

I also note that my SQLConnection is on an Datamodule, when i open
ReportExplorer a create a new Report and i look at Data Settings , the Combo
Property DataBase Name does not show the name of my SQLConnection component.
I think that the designer is not founding my connection.

If i use RBuilder 9.01 on D6 my application works fine.


Thanks in advance.

Hi Fabio,

ReportBuilder searches through each form and datamodule in your application
for a data connection. If you take a look at the GetDatabaseForName
property of the DADE plugin you are using (or ancestor), you will see the
code RB uses to do this. I would recommend tracing through this code to see
where the error is occuring.

I believe Interbase gives you an option to where/how the driver name is
stored. There have been no changes to the way ReportBuilder connects to
Interbase since version 7.04. Are you using a different version of
Interbase?

Hi Nico,
I will try to debug the source, but it is a little big , and i dont know
exactly where to put a break point.
But it is strange cause even the example source code from RBuilder (endUser
DataBase Interbase) does not work on Delphi 7(update1) Rbuilder 9.01. And
everything works fine on D6(update2) Rbuilder 9.01.
I have alredy reinstalled D7 on a diferent machine , and still does not
work.
Anyway..
Nico thanks for your help.
Best Regards.

Hi Fabio,

Try upgrading to the latest version of ReportBuilder as well and see if that
makes a difference (9.02).
