App doesn't work after I changed sencha 1.1 to sencha 2.0

[Tao636]

Hi!
English is not my mother tongue，so sorry for my pool English first.

I am a new developer and I learned my first app by this net:
http://www.onlinesolutionsdevelopment.com/blog/mobile-development/creating-a-sencha-touch-mvc-application-from-scratch-part-1/

It works well, but when I changed the sencha1.1 to sencha 2.0 it didn't work.

Could you please tell me why?

Thank you !

Hi!

there are major changes to be carried out when upgrading to 2.x from 1.x, like:-

• Different way of defining classes. in ST1, it was with extending and with ST2, it is defining (rather than extending)
• you don't need to reg your model anymore and model can be defined like classes

also, upgradation to 2.x have some othere changes.

you may find full detailed instructions and specification on upgrading to sencha touch 2 here,
