I'm a bit confused, and it's no wonder. I'm trying to add a custom metadata field to the Page Properties of all the Article Pages on my Publishing Site, and all its subsites. However, when I made the change by creating a Site Column in Sharepoint 2010 Designer, and adding it to the Article Page Content Type column list, the column did not turn up on my subsite pages.
Then I noticed that when editing Content Type columns, there's a button in the ribbon marked "Push Changes to Sites and Lists". I can't find any documentation as to how this button works, or even if it is a button at all, as clicking it seems to make it glow yellow, as if it's a status indicator. Even spookier, at this moment a Google search for "Push Changes to Sites and Lists" comes up with ZERO results!
So, let's open this up for discussion! What is this button for? I *think* it has to be enabled (i.e. glowing yellow) when I make a column change, but BEFORE I press Save, in order for any lists or subsites using the Content Type to register the change.
If I helped you out today, you can buy me a beer below. Cheers!
