NTP Binding lost on each reboot

Hello

I recently added a NTPbinding on my OPENHAB 2.1 project.

As a work with MQTT binding, my sitemap is a full manualy file.

I notice that I have to re-add the NTP binding in paperUI on each restrat of my Pi and my Thing that I’ve created (LocalTile) turns unitialized.

Thank you for your help

Here some details :

ntp:ntp:local  [ hostname="nl.pool.ntp.org", refreshInterval=60, refreshNtp=30 ]
DateTime Date 	"[%1$tA %1$td.%1$tm.%1$tY - %1$tH:%1$tM]"	{channel="ntp:ntp:local:dateTime"}
Frame {
   Text item=Date icon="calendar"
}

Are you using the addons.cfg file to load bindings? In other words, did you uncomment the line with bindings in this file? If so, you will need to add ntp there. If not, please disregard this post.

Yes a have add NTP in addons.cfg file but in meanwhile I change NTP to ntp
And it seems to work

Thank you form your reply
