[evince] How to clear radio-button on PDF form

[Luis Rosety <luis rosety gmail com>]

Hello,

I have found that wonderful soft Evince and its capacity on filling PDF forms.

I was filling a form and I checked a radio-button by error.

I don't know how to clear it because if I check other option of the same group, it checks both wich should be unallowed.

Is there a way to uncheck (clear) a wrongly checked radio-button on  PDF form? (without the need to clear the whole form, of course)

Thanks for your help and for this great application

Luis
