So, it's not exactly clear how I get the list of HasCell to the constructor.
I.e., if I have:
MyBean has a getter that returns List<String> - I would need to create, say, a ClickableTextCell for each of these, add them to a list and get that list to the constructor (marked with the ellipsis above).
ColumnConfig<MyBean, MyBean> myCol =
new ColumnConfig<MyBean, MyBean>(new IdentityValueProvider<MyBean>(), 100, "My Col");
It's not at all clear how to create this. I'm using GXT's PropertyAccess interface to provide the values for the columns.
