As I reported in "Adobe giveth and Adobe taketh away" (http://www.acrobatusers.com/forums/aucbb/viewtopic.php?id=25559), I was told the following by an Adobe employee:
"Currently, the Collab object applies only to "Browser-Based" reviews not "Shared Reviews" so it is likely that the object will either be changed or deprecated."
Does anyone know whether the Javascript variable "Collab.showAnnotToolsWhenNoCollab" will continue to be supported in Acrobat 10?
If it will not be supported in Acrobat 10, is there another way (either in Javascript or a plug-in) to expose the Comment & Markup toolbar?
There is however a general principle applied to all features of APIs ([b]though I'm not saying it applies here[/b]) that users are given at least one product cycle with a "depreciated" object before it's removed, unless the feature has been killed by a forced change (such as a security patch, or the loss of some external resource the feature relied on). This is to ensure as many in-the-wild documents as possible continue to work as the author intended, but there can be no guarantees.
