IModel> model
But how can I create / define such a model ?
I have used org.apache.wicket.model.Model in one project for example
like:
new ListMultipleChoice("id", new Model(), choises, render)

Re: AW: Null Model Error
You have a list of tagging keys that user can select and a render to it, but you don't have an model to receive the selection made on component.
