Page refresh or redirect on after button press

Question

Hi! 
 I have an issue with refreshing a page. I've got a read-only grid and a delete button. After I choose some of the rows a press delete, which launches "a!startProcess" function; the problem is that I don't know how to refresh or redirect in that case. I have no rule inputs or variables...

As Stefan mentioned, you need to be using the onSuccess parameter of the startProcess() call to do that save - the way you have it set up now, you're nulling out the customerIds too early, and any refresh that may have happened due to that change will have already happened before any changes caused by the process which you might want refreshed in your local data. 
 Moving the "a!save(local!customerIDs, null())" to "onSuccess" might work just on its own. But for code clarity, one trick I usually do is to delcare a separate variable i.e. "local!refreshCounter: 0", and then in my "onSuccess", i'll overwrite it with "local!refreshCounter + 1". Then just add that to the "refershOnVarChanged" list wherever needed.

That's better of course, though what I was really hoping was that you might edit the original comment to move the code into a code box.. 
 That said - I'd have to guess that what you have here should work, provided your process is configured correctly. What change is happening in the process that you'd expect to see reflected in the grid upon completion? And can you post a screenshot of your completed process instance?

Unknown said: OK. Your a!queryEntity does not know that it should refresh. 
 I'm a little fuzzy on this too, though I assumed since a!gridField() has its own "refresh on var change" then it might "know" how to force the queryEntity to refresh, similarly to having a queryEntity in a refreshVariable (the other primary thing that contains a "refresh on var change" parameter). 
 My current guess is that his process is not configured correctly - since if it doesn't chain all the way to the WTDS / DFDSE node that handles the "delete item" functionality (regardless of whichever method is being used), the data won't refresh from the StartProcess completion either way.
