I've been using dataobject manager for a while now with no problem. On one particular site (SS2.3.3 dataobject r206) I have a problem with drag and drop.
On a page with a dataobject manager, I can see the checkbox to allow reordering. But when I click it, I am unable to drag anything around.
However! Drag and drop reordering works fine in the 'Files & Images' section.
I'm adding the manager the way I've done countless times before...
$fields->addFieldToTab("Root.Content.TestObjects", new DataObjectManager( $this, 'TestObjects', 'TestObject', array( 'Name' => 'Name', ), 'getCMSFields_forPopup' ));
Anyone have any ideas?
