I’m using tryton 5.8 and I would like to know, how to open a report by wizard?
If it is possible!
You can open a report from a wizard if you return a StateReport as it’s done in account_asset module: account_asset/asset.py at develop · tryton/account_asset · GitHub
Note that 5.8 series are no longer supported, you should consider upgrading to a newer version.
If you want to have longer support you can use 6.0 series which are Long Term Support and receive support for 5 years since its release date.
