Question

In C#, there are observable collections. In Java how do I represent a list a models? Suppose I have a model Item. I want to show users a list of Items. Do I create a ItemsModel (notice plural, encapsulating an ArrayList<Item>) then in my ItemsView bind (listen to property change events) to that? This model will also need to listen to PropertyChange events from its underlying Item. Is this the right way of implementing this? Is there a better way?

A possible solution could be the Eclipse Databinding. It let’s you create a binding from your POJOs to certain SWT Controls. For your special case with Items, you could use the Master-Detail Binding mechanism, for an example see http://wiki.eclipse.org/JFace_Data_Binding/Snippets#Master_Detail
