for some reasons, I had to change an existing oleDB connection to an odp connection. I did this incrementally by adding the new db connection, then adding the datasources, the parameters and the relations to the report. After adding all the new odp components to the report, I remove the oleDB components in reverse order (meaning remove relations, parameters, datasources and db connection). This works fine.
Changing the database connection is only the first step. I also have to add some other report components to the report. These components include adding a new relation between two datasources. Adding the relation works, but then rendering the report throws an exception:
I can't explain to myself why this is happening. Because the types of the columns are all of Type int. When I try adding this additional components and the new relation to the report with the existing oleDb connection everything works fine.Parent Columns and Child Columns don't have type-matching columns.
I guess, you want to have a report to reproduce this bug/error but I have to disappoint you ... I can't give you such a report. Nevertheless, I hope I stated my problem clearly enough and you can help me.
Thx, greetings.
