Why is onItem commented out in dojox.grid.data.DojoData?

Submitted by rbondi on Mon, 03/10/2008 - 19:59.

In 1.0.2 there is:

// request data
        requestRows: function(inRowIndex, inCount){
                var row  = inRowIndex || 0;
                var params = {
                        start: row,
                        count: this.rowsPerPage,
                        query: this.query,
                        onBegin: dojo.hitch(this, "beginReturn"),
                        //      onItem: dojo.hitch(console, "debug"),
                        onComplete: dojo.hitch(this, "processRows") // add to deferred?

    }
    // console.debug("requestRows:", row, this.rowsPerPage);
                this.store.fetch(params);
        },

Roles of DojoData model and store, now and in future?

Submitted by Maine on Mon, 03/03/2008 - 11:50.

A month ago we were speculating about the roles of the model and the store. The model seems somewhat redundant when used with a store. Since there's no definite answer and improving grid integration with dojo.data was already mentioned in grid priorities I'd like to ask for some clarification of their current/future roles.

Problem with large tree

Submitted by crazycradd on Fri, 12/14/2007 - 14:30.

I have written my own tree demo using a combination of techniques and I get some very funny results.

I can populate the ItemFileReadStore from the server and display a single level tree via the parser and programatically. I then tried to display a large tree using the same technique and the parser fails to load any nodes and the programatically created tree only displays a single level.

I have used firebug to get the JSON response and populate a local file. I then re-run the tests ponting my store at the local file rather than the server to check the JSON object and this works fine.
