Hi all,

I have a gallery page with an image class that extends DataObject. I want to allow CMS users to add up to 10 images, using the gridfield. How can I impose this limit?

I guess I could use onBeforeWrite to check the amount that already exist, but surely there's a better way (besides, I'm not confident that would work with the GridFieldBulkEditingTools I'm using).

Possibly you could try to check the amount of objects for the given page in the objects canCreate() function and return false if the limit has been reached...
