Dear I think there is missing some function that will help to customize workflow and I think this will resolve also a lot of queries from users like this JRA-4812. Please could it be possible to add the INITIALIZATION part between the CONDITIONS and VALIDATORS parts? This is on the View Workflow Transition page, where you can add some conditions, validators and post functions. This is the same way but there will be possible to add some plugins to initialize the issue when the transition is started. This will be very usefull for default values of any filed on the screen that is associated with transition. Also this can be usefull for create (initial) transition where then will be possible to initialize any filed before the form is populated to the user. Also there will be possible to change requireness of any filed for the current transition. And lastly there will be possible to run any plugin that will be created before the transition is started. This actions is not possible to do by Conditions or by Validators because this is exatly between it. Thank you for answer. Best Regards
