ExtJS 4 has some pretty cool stuff inside. Besides that (yes I know it was said many times before but I have to say it) the documentation is lacking completness in many areas.
One point is the "Loading Nested Data" example.
You show how the nested data should look like
but not how the FORM should look like to load this data.
id : 12,
title: 'All about data in Ext JS 4',
body : 'One areas that has seen the most improvement...',
name: 'S Jobs',
message: 'One more thing'
Especially the naming convention for Associations is interesting.
It would be really nice if you could give at least a very simple example for that, especially because the "Data Package" is already a hughe part of the documentation and only this part is missing to make it a whole.
Thanks in advance.
