Now you can set fonts/typeface directly in InDesign while creating PDF forms. This feature is now available in latest InDesign CC version. Please upgrade to the latest release.

Just come across this thread...so, to save me time looking, does that mean I CAN'T choose font colour and justify my text to the right when creating a Text Field 'button' in InDesign?
I know I can do this in Acrobat but if I've got a bunch of Text Fields that need the text justified to the right, it'll take far to long doing them one at a time in Acrobat!
