Hi, I've written : <form ...> <input name="created:date" size="20" value="1971/01/01"> </form> Under my web page I'm able to change the value of my input tag (it's doing for it...) Well, but if I clean the field of my input I've this error : "Invalid Date-Time String" This is due to the filtered "created:date". So How to avoid a such problem and not raise a Zope error?
