Hi all,

I have a Class which is extended a few times, now when I use GridField, I use this to add a new holder for this class. Next, I wish the user to select one of the childclasses, as depending on that choice, the fields in the CMS should change to the proper CMSFields (using the corresponding getCMSFields()), however I receive errors at line x of core/Object.php when I simply put $this->class = [selected classname] in my onBeforeWrite. Am I missing some more clever feature of silverstripe to fix this, or is it not possible to change the classname of an object during save? I noticed Object->class is public, so I should just be allowed to overwrite this property right?

Friendly regards,
Maurice
