Date Picker of Date Element is not working

[woipro]

Iam using the latest Git-Version of Fabrik 3.1 and the latest 3.1.1 Joomla-version.
I created a List containing a date element and some other elements. When i open the form for this list, it looks ok.

Now when i cklick on the date icon, the form will be closed and the list view appears again and the new entry was saved with the default values.
So there is no date-picker available but the entry will be saved by clicking on it.

The error-console of my browser (firefox 21.0) tells me the following when i open the form:

Zeitstempel: 12.06.2013 11:50:23
Fehler: TypeError: b.fn.popover is undefined
Quelldatei: .../media/com_fabrik/js/tipsBootStrapMock-min.js
Zeile: 1

Zeitstempel: 12.06.2013 11:50:23
Fehler: TypeError: this.form is null
Quelldatei: .../media/com_fabrik/js/form-min.js
Zeile: 1

Could you help we with this please?

Thanks Hans
