Problem encountered in ezpublishcommunity-4.4.0 fresh install :
When creating/editing a policy security in the role administration panel, if I select a node or a subtree limitation for this policy, the node/subtree is not saved when I save the policy.
Also, after selecting a node, if I then select a subtree, the node I just selected is gone ...
I therefore didn't manage to configure any security policy with node limitation in ez 4.4, as the limitation seems to be deleted when savinf the policy.

Steps to reproduce

• create a new role
• add a security policy (content/read for example) and click on "limited access"
• next, add a node and/or a subtree in the limitations (the selected node is automatically deleted if I choose a subtree, even before saving the policy)
• click ok : the limitations are not saved
