EventBroker: Unable to register event subscriber.

[Telavian]

I asked this same question on StackOverflow here, but wasn't sure if this is a better place.

I am attempting to use bbv.common.EventBroker with Ninject and am running into a few problems getting things wired up correctly.

I currently am using Ninject factories to create an item and then, since I subscribe to events, use the eventbroker to do the subscription. However when the register method is called I get an error that I can not find any information for at all. I am not even sure what the error means.

**Error:**

   bbv.Common.EventBroker.Exceptions.RepeatedSubscriptionException occurred
  Message=Cannot add more than one subscription handler method of the same subscriber one topic: 'Method1'.
  Source=bbv.Common.EventBroker
  StackTrace:

    public ItemHelper(IItem item, IEventBroker eventBroker)

      eventBroker.Register(this);

Hi

This exception is typically thrown when the same instance is registered twice. Make sure that the object you created is only registered once on the event broker.

In the code you posted is no error (at least I cannot spot any).

Let me know if this helps.

Happy coding

I didn't notice it before, but the interface for the class also had the method attribute on it. Thus it was declared twice. However, I didn't see it until I looked at the interface.
Thanks.
