How can ı fix it ?

[mgod]

I looks like you didn't set an adapter for the token view?

[slm]

I use custom list view for suggestions. And when user click on ıtem, I call "addObject()" method. It is work perfect but sometimes I got crash. Can we implement null check for getAdapter() on performCompletion method or more sensible solve ?

[mgod]

It looks like adding that check should be fairly simple. Until I get a new version out with that change, I would set an empty adapter for the tokenview to prevent the crash

209 I implemented check for now. When you release new version, I could use it.
