loading EXT Js

NigelAlford — Mon, 27 Aug 2012 18:10:40 GMT

I'm having some browser inconsistencies with loading EXTJS and i'm unsure of the problem anyone have a second to look this through for anything big that I'm doing wrong?

Thanks in advance,

Re: loading EXT Js

I ran a quick test using your code and it looks like your app functions except for the Locate portion. In your code you are passing in two objects one for latitude and one for longitude into the projectPoint function. In order for this to work you need to modify your code to retrieve the actual values from the passed in objects. Here's a revised version of your app:
