Here are the five page definitions needed to demonstrate the issue.

Debug_PageIncludeChild_SampleUpdateInclude is the page you’ll look at for demonstration.

Before I go make 5 pages, which org are you in? Are you in 10.x or 11.x?

It looks like all of this is done with code instead of using declarative Skuid. Is there a reason why this is? Why not use the page include component Skuid offers declaratively?

The code was shorter - we were observing the same behavior with the declarative method. I’ll see about putting together the declarative pages when I have the time and will submit a new thread if I observe this behavior in a more recent version of the platform.
