      Description copied from class: `UIXCollection`
      Creates the CollectionModel to use with this component. The state of the UIComponent with the new model instance is not fully initialized until after this method returns. As a result, other component attributes that need a fully initialized model should not be initialized in this method. Instead, model-dependent initialization should be done in `postCreateCollectionModel`
      Specified by:
        `createCollectionModel` in class `UIXCollection`
      Parameters:
        `current` - the current CollectionModel, or null if there is none.

    - #### enterContainer

          public final void enterContainer()

        `TreeModel.enterContainer()`

    - #### exitContainer
