Sencha ExtJS Grid with autoLoad Store never loads data

Lesson learned yesterday: Never use Sencha ExtJS autoLoad, especially when working with a Grid panel. I ran into a problem where my grids kept showing a “loading” message, but never loaded the data. Or, more accurately, I should say that they rarely loaded the data. Sometimes they would load the data, but I could never get them to load the data consistently. Then I found this solution, which seems to work well.
