I am trying to populate a jqGrid with data from a web service. I have looked at the jqGrid code and documentation thoroughly. I need another set of eyes to look at the code below and tell me if I'm missing something. As you'll see in the code, I have the grid set up to load when the page loads or during a refresh. After the grid load...

Any help...
