I think in controller you are correct , what about view are you defining the items attribute path
Sorry I missed the curly braces in the previous reply ...
<Table id="Travel" items="{/dataSet}" > //dataSet is the entitySet of the Odata service
if you still face an issue, send me the F12 developers option console screen shot.
And also please check in Networks tab of F12 options that data is coming from the back end?
Thanks
