Re: data store

Jared,
Thanks for the response. What I want to to populate a
dijit.form.FilteringSelect with an object of the form

pageJSON = {
identifier : 'id',
items : [
{ id : 'a', label: "Letter A" },
{ id : 'b', label: "Letter B" },
{ id : 'c', label: "Letter C" },
{ id : 'd', label: "Letter D" }
]
}

Honestly I don't want to use a datastore to do it. Seems like a
complete waste of memory and CPU. However not using a datastore does
not appear to be an option. So baring that, I want to populate a
datastore with the above object without having to read it from the
server. I already have the data it was pulled from the server in a
much more complex format and is being used for may things. the above
sample is a derived subset of that data.

what I'd love to do is this:

dijit.form.FiteringSelect.store = pageJSON;

baring that I'd like to do this:

store = new dojo.data.SomeKindOfStore( pageJSON )
dijit.form.FilteringSelect.store = store;

What I don't want to do is go to the server for data I already have.

Any advice or direction ( god knows i'm completely spun around at this
point ) would be greatly appreciated.

Vance
