Editing static files - changes not recognized by Application
I've uploaded a txt file into the static files area of my application, and I'm able to refer to the functions within it. They're working great. Now I'd like to be able to modify one of those functions.
Under Shared Components > Static Files, I click to open the existing static file. I make a change to the file and click Apply Changes. It's a very simple change: one of the functions returns hex code #FFFF00 (yellow), and I changed it to return #FF0000 (red).
I log in to the application, make a change to a field that should fire the color function. Yes indeed, that function DOES fire. Unfortunately, it produces the OLD result - I'm still seeing a yellow field.
However, if I delete the static file and upload it again, I get red as expected.
Am I doing something wrong, or missing a step to "activate" the changes that I make online?
