Can I use two cgi-callout together?
1) It depends on how your calendar widget works. Under normal circumstances, you'd clear a field by IWDatacapture.getItem('/path/to/field').setValue('');2) You can only have one callout per field. As a hacky alternative, consider using a text field beside it with a blank label and size=1. Your second button will be off to the side, but it'll be there... A better alternative would be to use a <callout> (not cgi-callout) and then catch the 'onCallout' event to show an option to select which callout to open. This could be as simple as showing a JavaScript prompt() or as complex as a jQuery dialog.
