custom dialog break css with no radio

[jmlpinaEtec]

When using a custom dialog and one of the elements (labels, buttons, radio)does not have an entry in the css, it breaks in the function StyleHelper -> font.getName().
In our case a valuelist and we did not have an entry in css for 'radio'.
We solved, create an entry for that element in the css. Ideally, a default font should be set if you don't have for this type

Thanks a lot
