Calendar widget event creation error when using a data store

[personeni]

I used the calendar example provided on the site and it works well, I can display, create and edit events.

I then set out to collect events from three xml sources (as opposed to the autogenerated ones in the example) and display them in their respective calendars. => works well BUT it makes me lose the ability to create events (edit still works though)

When I do try and create an event the Firefox web console gives me: TypeError?: this.getRenderers(newItem) is null.

Given that no one has shown interest in creating a patch in the past 3+ years, I'm closing this as patchwelcome.
