I am trying to follow this simple tutorial on Sencha Touch http://dev.sencha.com/deploy/touch/getting-started.html

I keep getting the JavaScript error: Uncaught TypeError: Cannot call method 'on' of null

This relates to the Map.geo property which is not getting set correctly. I am using the eact same code as on the link. I have tried putting on another box, in case it was a firewall issue, but get the same error.

    Found the answer to this. Turns out that the tutorial is somewhat out of date compared to the latest source code. The following should work: Instead of getLocation:true in your javascript file, replace it with useCurrentLocation:true – Adrian Westlake Feb 22 '11 at 12:32
  • Have some +rep as I was stuck on this too :) – Chris James Mar 01 '11 at 11:11
  • You definitely deserve some rep on that one. Was banging my head just now on it. – stan229 Mar 10 '11 at 16:30

    I've actually found this to be a problem with Sencha in general. A lot of their tutorials and documentation is out of date with the current version. Oftentimes, finding what you're looking for is a huge mess. – Munzilla Apr 12 '11 at 20:12

In your Application JavaScript File, replace getLocation:true with useCurrentLocation:true.
