I can't get the dynamic date formatting to work.
I made a server Connect Action Executor, but when i go to the 'Formatting' tab in the Calendar 3 popup and select the dynamic option the black thunderbolts disappear and are replaced by the (old) yellow ones.
The action executor is not visible in the 'Data Source' selectmenu.
What to do...

I had the same problem and ended up using HTML5 data bindings and created a data source. This then showed up in the list but now the page reports an error "HTML5 Data Bindings Required!"
The date picker is on a bootstrap 3 page and is not working i.e. no popup.
It appears that this extension has not been updated for Server Connect and HTML5 data bindings has been deprecated which causes the error.
Unfortunately my project is based around a dynamic booking calendar and at this time is at a standstill.

Popup is now working. Looks like the main issue now is that the extension is not ready for Server Connect.

Hello, as i explained in the other topic, mentioning this issue - the Calendar needs a small update, to be able to use Server Connect data sources. I will let you know as soon as the update is available.

Hello, we've just updated DMXzone Calendar 3 and now it is fully compatible with the DMXzone Server Connect data sources. Please update to the latest version!
