Dear jqwidgets Support Team!
I use jqWidgets together with AngularJS; therefore I use jqxGrid this way: <jqx-grid jqx-create=”gridSettings” jqx-settings=”gridSettings”> …
This will add the apply(..) Method to $scope.gridSettings.
However, I encountered problems having two concurrent jqx-grid widgets in one controller: none of the apply() methods of the settings object will work anymore – “undefined” is not a function is raised, if I like to call apply (before having a second grid, it worked well).
Instead of using apply over the settings object, I use now e.g. jqx-instance=”mygrid” attribute to have $scope.mygrid accessible and then, I can successfully call $scope.mygrid.apply(..).
Is this a bug? – I currently have no minimal example, since I have not yet the time to stripe all around to have it minimal – I assume that you will be able to quickly test this (e.g. by just making a master-details example for AngularJS) 
Thansk in advance for your help!
best regards,
badera
