I would like to configure all my projects as though they are for Joomla 3, but in those instances where initially the release will be for Joomla 2.5, the ordering box is causing me issues.

If I set ordering in in the views to the new 'Draggle' ordering that J3.1 uses, but export the project using the J2.5 config, I get a little cross but obviously no draggable functionality. So I / we dont need to go through all our views when upgrading, can we make it so that Joomla 2.5 will ONLY export the old style ordering method by default regardless of what is in the view of the project. That way we can create a J3.1 package with zero need to reconfigure anything

Unless of course you are implementing your own version of draggable ordering for J2.5, hence the fancy little cross

Use 'Sortables' for ordering. 'Ordering box' is gonna be deprecated completly in future.

For you, it is was jQuery version issue.

Upgrade jQuery and jQuery UI (Sortables), or try in the new version 2.6
