A missing piece in Prototype helpers



I wanted to use select helper to provide a parameter for a function call
and could not make it work.

I wanted to do this:

page.call ‘Field.activate’, page.select(’#customer_form .edit-form
div.fieldWithErrors input’).first

and ended up writing pure Javascript:

page << 'Field.activate($$("#customer_form .edit-form 

div.fieldWithErrors input").first());’

If someone can figure out the way to get it to work without << operator,
please post.
