I want to use autocompletion to select one or more authors:
<input-many:favorite_authors>
<name-one complete-target="&@user" completer="new_favorite_author"/>
</input-many:favorite_authors>
However, the name-one dies when a form for a new model is being displayed:
ActionView::TemplateError (You have a nil object when you didn't expect it!
The error occurred while evaluating nil.dasherize) on line #65 of
app/views/users/welcome.dryml:
The crash is in the name-one tag:
class="autocompleter #{type_and_field.dasherize}"
When the form is first being rendered, the collection is empty so Hobo
creates a fake-field-context. type_and_field returns nil for the
fake-field-context (an array doesn't respond to :typed_id), we end up
calling nil.dasherize, and Ruby bombs out.
This patch appears to fix the problem...

Is this the proper fix, or is something more insidious going on?
