Steps to reproduce:
1. Create approx. 30 scheduled events
2. While does events are being created, open the add event wizard
Once the request creating the 30 scheduled events returns, the state of the Add Event Wizard is reset. This makes the behaviour of the Add Event Wizard quite undefined: Adding an event while a previous request is still running might work or fail more or less arbitrary depending on the timing.
Either don't allow to open the add event wizard while the events are being created (e.g. not close the modal window) or make sure that the Add Event Wizard works with pending "new event" requests.
Workaround (if any):
