Hello Lemon,

In general, we've got some issues related to the data prefetch (the items with 'Loading..." text), but it fixed in the latest internal build and recently released BETA version of Q2 2015 release. You can try a newer version of Kendo UI.

With regards to the particular setup, you will need to define a valueMapper callback. Even though the binding is local, the widget still does not know selected items in which exactly is present after filtration for instance. You will need to develop a function that maps selected values to item indices.

Hello Lemon,

Thank you very much for the repro demo. Indeed, the widget does not populate some of the items. I believe that the issue is related to a "race" conditions due to the local binding. I logged the issue in our Github issue tracker.

I am afraid that I will not be able to provide any workaround in this case.

I updated your Telerik points because of the involvement.
