Hi,

I have an application that registers a set of dmcc extensions at its start up process.
Sometimes if the application crashes or it is forcedly stopped, the extensions remain registered for a couple of minutes and if I try to start up the application it is not able to register again (so I have to wait a couple of minutes before trying to register them again). I get this type of exception:

Is there a way to force the registration (unregistering/registering again), so every time I start my application I will be sure all extensions will be registered?

thanks,
Renato

to make it easier to understand, the cause of the exception, when I try to register an already registered dmcc extension, I get:

Caused by: ch.ecma.csta.errors.ResourceBusyException

As far as I know, it is not possible to register a DeviceId if the same DeviceId has already been registered. Possible workarounds are:

1. If possible, reconnect the old session instead of connecting a new one.

2. If the registration fails, try again with a new DeviceId using a different instance (0-2).

3. When getting the DeviceID, set controllableBy OtherSessions to true. Then, if the registration fails, your application can unregister the device and register it again.
