How to show wait message that is used by actions

A little more info…I moved the blocking back to the row action framework and add one of my field updates before the snippet call and “seeing the simple field update and all the changes caused by the snippet” occurs after the blocking of the UI has started. So page is unblocked while action in and outside of snippet are completed…then changes are applied to the screen…then screen is block

See seq of actions:
Show Message and block UI (2 sec)
Update a field on row(2)
Run a Skuid JavaScript Snippet

I’ve removed the snippet and repeated this and the blocking still occurs after the update field action is complete.

it really appears as if the blocking is only useful when save or requery occurs…then you can lock user out until the database level stuff is complete.
