I wrote a simple context file for pdf form filling. Translates fine, but the resulting pdf simply shows text but no fillable forms. What’s needed to actually get forms?

Here’s the tex code:

% interface=en tex=pdfetex output=pdftex

\starttext

Field 1: \fillinfield[name]{text that defines field length}

\definefield [Email] [line] [ShortLine] [] [pragma@wxs.nl]

Field 2: \field [Email] [your email]

\stoptext

Thanks!
