Uncaught Error: Template must be cleared before a new bindingDelegate can be assigned

[Mohamed Anouar ABID]

Hi,

What means this error please ? And how can I resolve it ?

I am just trying to use a element <choose-date> </choose-date> into a schedule.html page.

If I delete is=auto-binding sentence in the template tag, the page will be displayed without errors but without binding of corse.

And when I use the auto-binding the " Uncaught Error: Template must be cleared before a new bindingDelegate can be assigned " is displayed in the console.

Thank you
