// setting up the binding for my table here, this works ok:

        contentBinding:   'Training.operativesController.arrangedObjects',
        selectionBinding: 'Training.operativesController.selection',

// then trying to access the selection in the console gets this:

  Training.operativesController.selection.get('firstObject')
  TypeError: Result of expression 'Training.operativesController.selection.get' [undefined] is not a function.

// Just the selection outputs this:

  Training.operativesController.selection
function (key, value) {
        
    var old = this._scsel_selection,
        oldlen = old ? old.get('length') : 0,
        content, empty, len;

    // whenever we have to recompute select.........
