Ok, maybe you are right that adding such method to PropertyModel will make it bloated, but I think that some model dedicated to work with maps(MapModel ?) will be nice feature of Wicket.
I know that questions bellow dont stick to the subject of this thread but maybe you can help me with them. Recently i started to 'study' Wicket API and Wicket sources and have two questions(so far ;)): 1)What IChainingModel interface is for ? I thought that it will be used inside model implementations in getObject method checkig if nested model object is a ChainingModel object but the instance of operator in this methods checks against IModel interface (what is correct). If I understand Wicket API correctly it is possible to implement some model with chainnig ability without implementing IChaininig model - its internal implementation of get/setObject methods. Could you explain me what I(or rather my model) gain when my model implements IChaininigModel interface ? 2)When I looked at getTarget() method inside PropertyModel class I found that retriving of model object is done inside a loop. I dont understand why PropertyModel cares about how nested model is implemented. Why it cares ? because it checks if object returned but nested model is another nested model or not. I thought that retriving of model object is responisbility of each model class individually and PropertyModel should only check if its model object is IModel object (if so return ((IModel)myModelObject).getObject) or is it a 'real' model object(if so return it). Answers for this questions will help me implementing my MapModel class.
