View Full Version : Problem with Ext.data.Reader sample code

I was having a problem with my Ext.data.Reader so I tried the sample code in the documentation but am getting the following error:
Uncaught TypeError: Cannot read property 'length' of undefined

Ok. I have a little more information on this. I was working with a TreeStore and a NestedList and got the same error. I tried the NestedList page in the demo and it also got the same error.
The problem is when you have to read the file locally instead of from a webserver you get this error. I moved my code onto a webserver and it ran fine.
However, I still need to solve this problem as I'm planning on distributing this in a PhoneGap application and would prefer to not have to download the json data. However, I also don't want to load the json data until the user goes to that page in the web app. So I figure that there's two ways around this.
var fileref = document.createElement('script')
which might work but is ugly and kind of a hack.
2) Use some other way to call this I don't know about
3) It's a bug and needs to be fixed
