Is there any way round this ? I'm about to add transaction support but I us=
e
an administrator session to retrieve an acl from the content to decide
wether the user has access to the node or not. How has everyone else dealt
with this problem ? I guess I would have to change the code to do the acces=
s
check prior to starting the transaction ?
