With databinding is there a way to have it default convert all empty
strings to null? I know I can do this with a converter, but I would need
to attach it to every binding. Any help would be greatly appreciated.

You can do it in a custom UpdateValueStrategy by either setting the
IConverter or overriding createConverter(Object fromType, Object toType)
You'll still face the problem of getting that UpdateValueStrategy used
on all your bindings. One way to do that is to funnel all binding
creation through a single place; another approach is to create a custom
DataBindingContext and override bindValue() so that it uses your custom
UpdateValueStrategy as the default (when null is passed in).

There might be another way to globally apply a strategy or converter,
but these are the options I know about.

Hope this helps,
Eric
