GetChangeTypeParameter(Parameter param) - how to specify param

[wim]

I wonder how I can invoke the command GetChangeTypeParameter(). I have no idea how to specify the parameter. Does anyone have an example of the usage? thnx

From TBC:

ElementId paramId = new ElementId(BuiltInParameter.ROOM_NUMBER); 
UpdaterRegistry.AddTrigger(GetUpdaterId(), elementFilter, Element.GetChangeTypeParameter( paramId));

It seems to work only with built-in parameter.

In fact, you can watch any kind of parameter as shown in this post: http://adndevblog.typepad.com/aec/2013/01/dynamic-model-updater-with-project-parameters.html but you need to have at least one element bound with the parameter in order to retrieve it.
