[tryton] Generating warnings during report run

[Jon Levy]

I am wondering what the correct idiom is to issue warnings while running a report. Reports do not inherit from WarningErrorMixin, and run in readonly transaction. I have a report that requires quite a bit of computation, and I would like to be able to possibly issue a warning.

If I try to call the warning based on a Model (that I am otherwise using in the report), it raises an error that it can't be done in a readonly transaction.

Is it appropriate to raise the warning with a Transaction().new_cursor context manager?

I think it goes against the general idea of having Report being
readonly.
Indeed I think you should run a wizard that will raise the warning or
launch the report.
