You need to register the base method in the ArrayList class.
Then your callBaseMethod should start resolving. However, you need to make one more small tweak - the arguments to the base method are passed as an array of arguments. So you would have:
Juicy.UI.TabPageCollection.callBaseMethod(this, 'add', [tabPage]);
