Question
Is anyone experiencing issues with incorrect managed package apex class visibility? Suddenly unable to save a class and everything seems to be in order. What am I missing? Anyone run into this or have workarounds?
Update
Seems like this is an issue with the Tooling API. Was using Sublime Text 3 + Maven's Mate, and switching from Tooling to Metadata apex compilation (which I seem to do daily now) resolved the issue.
Background
Editing a class that refers to a Zuora class.
Zuora.OnDemandSyncManager syncManager = new Zuora.OnDemandSyncManager();
Previously this had saved fine, but now I'm getting the following error
Package Visibility: Type is not visible: ondemandsyncmanager
However the constructor is listed as global when I view the installed package components (v2.4)
Which matches the version settings for my class.
