I don't remember anything on this topic.
A quick suggestion:
- Don't use a real object, instead dynamically create one using
scripting, without saving it (#set($o = $doc.newObject('Your.Class'))
- To remember selected options between requests, put the object in the
URL, or in a form
- To reload the state from the request, use
$doc.updateObjectFromRequest('Your.Class'). This method automatically
creates a new object if one doesn't exist, so you don't even have to
call newObject. Just use:
#set($o = $doc.updateObjectFromRequest('Your.Class'))
