[URGENT] preventing node delete with policy

[tonc]

Hi all,

I have a policy that automatically adds/removes associations depending on the content.
I would like to be able to block a delete of a node if it is the targetnode of such an association.
What is the best way to do this? Just throw an exception in the beforeDeleteNode() (when using BeforeDeleteNodePolicy) or use some kind of lock/permission together with the association?
Help would be greatly appreciated!

Greetz,
Toon

Do the check in beforeDeleteNode() and throw an exception.
