It looks like this is a SSL to non-SSL issue which still causes a cross domain Ajax call even though they are on the same server. Now, does the URL paramter allow for https connections?

What are the constraints around the “url” parameter?

I've found that the grid will populate with items in the modern browsers when I have the url parameter set to localhost:8080 –

Grid at location: http://localhost:8080/app1/grid

URL parameter: http://localhost:8080/app2/items

However, when I deploy to my Dev system, and I use the name of that machine, the grid no longer populates –

Grid at location: http://my.machine.net:8080/app1/grid

URL parameter: http://my.machine.net:8080/app2/items

Same machine. Same domain. Same port. No grid items..

Thanks!
