Looks like the JS code disables any submit button inside a form if the
button has no "name" attribute, so a workaround would be to give the button
a name:
BUTTON(icon_text('Export', 'print'), _type='submit', _class='btn', _name=
'export')
Perhaps there should be a more elegant way to prevent the automatic
disabling. Feel free to submit a Google Code issue about this.
