问题
My grid isnt showing data when put to tab. This grid, store, model, JSON are working when renderd to body or div, or as a part of a viewport. Only not showing when put in tab, that is also created using JSON and Tree! This is a (sometimes)working example. I cant figure it out, maybe scope bug ... Please help!

JSON for TREE

JSON for GRID

{"name":"Bart", "email":"bart@simpsons.com", "phone":"555--222-1234"}

ok... i have tes your code just by copy paste to my firebug (of course with edit the json urls),
and i got an error.... This is because the program flow...
if it was your script, and put them in a single file, you specify a grid before the store
here code works for me no error...
