Steps to reproduce

1. See JSFIELD-34

Expected results

• Usage of a JS field should not tamper with other fields in the form

Actual results

• JavascriptField binds to data when the field is created
• to do so it access internal FormPresenter and call getBinder()
• this method though tries bind all finds a if a binder for the given locale doesn't exist
• this is called way too early (the other fields are not created yet)

Workaround

Skip introspection if binders haven't been created by UI framework yet

Development notes

The module heavily accesses private API which can be changed any time/any release.
