angular-xeditable: valueGetter.assign is not a function

Hi,

I get the following when saving changes in a table row.

TypeError: valueGetter.assign is not a function
    at EditableController.self.save (xeditable.js:791)
    at xeditable.js:1261
    at Object.r [as forEach] (angular.js:323)
    at Object.base.$save (xeditable.js:1260)
    at c (angular.js:1008)
    at applyCallback (xeditable.js:1539)
    at Object.then (xeditable.js:1534)
    at Object.checkSelf (xeditable.js:1249)
    at angular.js:1003
    at applyCallback (xeditable.js:1539)(anonymous function) @ angular.js:11655$get @ angular.js:8596$get.n.$apply @ angular.js:14567(anonymous function) @ xeditable.js:1453c @ angular.js:3032

Any idea of what can cause this?

Best,

Søren
