Question about error message

Hi,

the error message is a message that stems from JavaScript/Java. For errors from those programming languages, you're not limited to the ARIS forums to find help. You can look up your error message on websites like stackoverflow (or simply use the search-engine of your choice) - chances are high you'll find posts like this:

https://stackoverflow.com/questions/8327514/comparison-method-violates-its-general-contract

where people write anwers like this:

You probably wrote a custom method that you plug into an array.sort(...) function, that's the thing that is causing your error. You should rethink your sorting method.

Without you showing any code of your report, this all the help I can give you.
