Forgot: I'm using tacos-lib-20050421.jar, because I thought this was the last jar to support T3 (the other tacos jars are named tacos4)
I have not provided the keyProvider, state and sorter bindings, because the documentation says that these are optional and the defaults are good enough for me I think. I have provided the bindings contentProvider and value, which I think should be correct and non-null all the time. Maybe my next step should be to include bindings for keyProvider and state, maybe that helps. Thanks for the feedback!
