Can't use the script object - there are multiple scripts in play because
one script "includes" other
As I said: *only* access checked objects can be shared with other contexts.
In your case only the object created from |obj_template| is access checked,
and hence only *that* object can be shared.
In this case you use the template to create the global object underlying
the global proxy, so that
But I called SetSecurityToken to set different token for each context. I
commented out the SetAccessCheckCallback calls to let access to be
controlled only by SetSecurityToken. Even if I add
"SetAccessCheckCallback(AccessAlwaysBlocked);" statement, the cross access
are still allowed in
If you have two contacts with different security tokens you're only
allowed, as an embedder, to leak explicitly access checked objects between
the two. Hence only objects that are backed by object templates with access
checks.
The reason is that we don't check whether you have access for all
