Thanks in advance.

Are you receiving data from the backend?

[siva565]

first time i'm receiving data from backend. But when i'm trying to load the same page again every thing displays fine except grid data.In this case firebug call shows empty(nothing).

OK, so if on your second call if you get no data, this is why the grid isn't showing anything. Afraid to say that it seems like your backend is doing something and not returning data.

but with out using caching it works fine.

So if you use caching in Codeignitor it doesn't work but if you turn off caching in Codeignitor it works. Sorry, but that's a Codeignitor issue.

so is there any alternative solution for this caching in extjs? i want to load my web site fast.. how can i achieve this? is it possible?

[mitchellsimoens]

Sure it's possible. Have you tested Codeigniter to make sure caching is working? Like go to the controller to see if you can get data? ExtJS and Codeigniter are separate and shouldn't really affect the other. If you need to specify parameters or change the names of parameters, that's pretty trivial to do in ExtJS.

[siva565]

yes..i tested every thing.codeigniter caching working fine. when i'm using caching it works well for all pages except extjs grid,form,tabpanel, etc...
