....someone could help me ? I can't find anything about this.
Thanks Bård for this new step.
So now it display the integrer 0 or 1 but what I want is a "real" checkbox whose result can be send by mail with the other elements of the form.
Any suggestion ? Thanks
To get checkboxes on information collectors you would need to use strings at this time. If you just change the template of the attribute you would like to be shown as a checkbox to use <input type="checkbox" .../> instead of using <input type="text" .. /> you will be able to fetch the input from the text box and it will be stored in the database.
Checkboxes/boolean do not support information collection yet, so you have to use this workaround.
