IllegalStateException with No Bindings

[dkpalmer]

I realize this is a bit counter intuitive to the intent of the library, but I ran into the following exception when I had no bindings defined in my Item view model:

java.lang.IllegalStateException: Could not bind variable '3' in layout '<...>/item'
    at me.tatarka.bindingcollectionadapter.BindingCollectionAdapters.throwMissingVariable(BindingCollectionAdapters.java:276)

I ran into the exception while stubbing classes and layouts out to test the library. When I added a binding in my layout, everything worked fine. It seems like things should still work even if I decide not to have any bindings in my item layouts.

The check is to ensure that the variable you are trying to bind to actually exsists in the layout. This way you immedatly know if you forgot to add it or use the wrong one. If you don't want a binding you can use ItemView.BINDING_VARIABLE_NONE.

There is currently a bug in the databinding library where if you declare a varibale but not use it in a binding it will return that it doesn't exist. This will be fixed in the next release.

Got it. Thanks for the quick response.
