I'm a newbie, but have successfully implemented an IO Node with a static node model using defaultnodesettings components in the dialog. The node is very generic and to make it more user friendly I need to retrieve some metadata from our server solution first, which I currently do in the dialog. Depending on that data I need to extend the node dialog and the model, however, I cannot create new dialog components, because I cannot bind them to a settings model, because it doesn't exist yet in the model and I don't know how I can create it dynmically. I'm afraid I'm missing something here. Any suggustions howto deal with such a situation would be highly appreciated.
