UX_V12--25 Alpha Five V12 Synchronous script execution

Ajax callbacks execute 'asynchronously'. That means that if you have defined an Action Javascript script with a series of actions (such as 'open grid 1', 'open grid 2', etc.), the actions run in parallel, not sequentially. In many cases you will want the actions to run sequentially, and this video demonstrates how you can easily convert an Action Script from asynchronous execution to synchronous execution.
Note: Also applies to the Grid component.
