Hi
Generally I think DataObjectManager is a great adition to Silverstripe and have used it a number of times now.
I have recently used it to manage sets of linked sitetreepages and use the SimpleTreeDropdownField which works beautifully. However I would like to make this a required field. I can't see any way to add a validator for this form. I would really appreciate it if someone could tell me if it is possible and if so how?
Unfortunately, no. That's a major limitation of the module right now. There were too many javascript conflicts, and even when they were working together, the page load time was ridiculous, so I ended up just disabling validation. Once Silverstripe drops jsparty in 2.4, it will be much easier to implement.
Thank you for replying uncle Cheese. I'll look forwards to the arrival of 2.4
