Comment 4 for bug 710689

Hello Marco,

          First thing is here constraint is valid for periods, so if you have periods defined for one company and you try to modify it then it will raise warning to user.

          And for installation of chart for any country or generic chart if you have fiscal year already defined as demo/manual creation and you try to set/modify it start or end date in configuration wizard of that country it will raise an error to you (Here in code we do like: we search for start and end date given in configuration => if the fiscalyear exists we can not create new fiscal year for that company and if the fiscal year not exists we will create it).

        Here the main problem is it raise warning to the user and then user click configure it pop up error ( KeyError: 1 ) second time.

So i request framework team to fix it then we can check for the possibilities fixed for Addons module.

thanks,
ara
