Page Title buttons not processing Merge Syntax

I have applied update 4.  The merge syntax is working on a page title but not in the button.

So… Buttons don’t listen for changes in the model data.  So when you select your button and change the value of your field - the button isn’t listening for the new value and doesn’t get updated. 

You might get what you are after using conditional rendering 4 different buttons. 

Yes, but I was trying to get around recreating a long list of actions under 8 different buttons.  Is it possible to save a long list of “actions” that could be referenced?

Wouldn’t it be nice. 
You can jump to the XML and copy the actions,  but that gets pretty closed to coding…  Caveat lector

No problem. Was just getting lazy.
