Caution: it will call model#getObject. Given your explanation I don't think your model is a LDM.

However, if you change the model object dynamically/afterward, you have to use #set[Default]ModelObject instead of #set[Default]Model. > With the first, the default model is still null. > No sure to follow here, because you said you initialized the model with an empty list... So neither the model and the modelobject should be null... > > Thanks, Chris > > >
