Invalid bound column name

Greetings,

So a colleague of mine is working on a report and has received an "Invalid bound column name" error. She also received the following error along with it: "In nested aggregation, all the non-constant expression must have same group level.".

We have been doing most of this by copying a table with it's bindings and modifying the bindings slightly to function as we want, and there are no problems. The problems occur when we delete, in our case, 9 column bindings and their corresponding data elements. We then replace the data elements with aggregations of the same name as the data elements so we do not have to change about 50 other bindings that pull from them.

We are using BIRT 2.5.0.

If you have any insight as to the problem, we would be happy to try anything about now.

Thank you,

Jordan Trulen

Can you check the desginerValues in the xml view and remove the column names from them? I could not reproduce the issue in 2.5.1. If you can recreate the issue using the classic models db please post it.

It turns out that she managed to find the problem. It had something to do with using bindings from both the dataset and from the table both in the same aggregation. Once she corrected that, she fixed the problem.

Thank you for your prompt reply.
