get JSON data not mapped to store

[choykawairicky]

Just wanna ask is that
1.) the grid would not load & save the JSON data which have not mapped(that is some columns would not display in the grid) to the store?
2.) if this is the case, is it I need to load data to a Jasonstore first, and use that Jasonstore as the store of the grid....whenever I need the data which is not displayed, I'll need to get it from the Jasonstore i/o the grid's store

the grid needs a store regardless of how you do it so your questions are kinda confusing.
in any case, every field thats mapped in the reader will be available to the grid (and anything else by accessing the store directly), and only those fields specified in the grid's column model will actually be displayed (though once again all fields are still available in the records for things such as custom renderers).
