I am having to right-click a tag or UDT instance and select restart for changes to take effect.  
More specifically, when a tag an associated data property is bounded to in an alarm changes, the associated data property value does not change. I have to restart the tag for the associated data value to change.  
Why is that? Shouldn’t it change because the tag its bounded changes?

Also, when changing a binding in a UDT, I have to restart the UDT for the change to take place. This has happened on an expression tag.  
This shouldn’t be normal behavior should it?

IIRC, those are evaluated (and therefore change) when the next alarm occurs.
