listfoot and paging disappears when loading data

Load some data using MVVM in a listbox. The listfoot and the paging will disappear when data is loaded.

The used code can be found here: http://zkfiddle.org/sample/1sjecrj/1-Hide-Auxhead

Execute the page and click the "load data" button. It works fine in Fiddle with ZK 7.0 but when running it using ZK 7.0.2-FL when the data is loaded the listfoot and the paging disappears.

Tested with ZK 7.0.2 and ZK 7.0.1. In both versions the behaviour is the same
