Updating the Thing Structure HELP

Setup, Configuration and Use Runtime
1

Hi guy’s,

In the documentation is said that it is possible to change the structure of a thing by adding, or removing channels. I tried the example in the documentation

public void thingStructureChanged() {
    ThingBuilder thingBuilder = editThing();

    Channel channel = ChannelBuilder.create(new ChannelUID(getThing().getUID().toString() + ":test"), "Switch")
            .build();
    thingBuilder.withChannel(channel);
    updateThing(thingBuilder.build());
}

but I am getting the following error:

Has anyone of you tried to add channels dynamically?

Best regards, Haris.

Hi Haris,

I general, I would suppose it to work…
As it is related to code from Eclipse SmartHome, may I ask you to post your problem there? https://www.eclipse.org/forums/index.php/f/271/

Thanks!
Kai
