Iterate on properties - Feature Removed?

Continuing the discussion from Platform Update - Release Notes– 06/23/2015:

Was the ability to iterate on properties removed in this platform update (or a recent platform update)?

9:07:58 PM: error java.lang.SecurityException: Invoking methods on class org.codehaus.groovy.grails.web.binding.DataBindingLazyMetaPropertyMap is not allowed: each @ line 417

Sample Code:
(where subscription is the result of a subscribe() call or grabbing a subscription from app.subscriptions)

subscription.device.properties.each { prop, val ->
        log.debug "property: ${prop}; val: ${val}"
}

iterating on properties works fine.

using

which is the thing you can’t call a method on, or the thing with the behaviour change per your other post.

Perhaps subscription.values().device.properties.each would work? or
subscription.get(“device”).properties.each?

Good catch. It does seem to be related to the subscription issue. If I get a proper device object, the code works.
