ComboBox: support dojo.store

[bill]

Enhance ComboBox to support connecting to a dojo.store by default. If ComboBox is created with a store parameter that's a dojo.data Object, then require() dojo.store.DataStore and use it to wrap the dojo.data store Object, converting it into a dojo.store.

[bill]

(In [24654]) Enhance dijit's ComboBox and FilteringSelect to be able to source from the new dojo.store API. The old dojo.data API will be supported until 2.0.

Change dojox.mobile.ComboBox widget to source from the new dojo.store API rather than the old dojo.data API.

Add cancel() ability to dojo.store.DataStore?, to be able to cancel a fetch running on the underlying dojo.data store.

Fixes #12373 !strict

[bill]

(In [25502]) Support ComboBox.store.fetch() for back compatibility. Only pulls in ObjectStore code if/when fetch() is called. Refs #12373 !strict.

​http://bugs.dojotoolkit.org/browser/dijit/trunk/form/FilteringSelect.js?rev=24654#L210 and ​http://bugs.dojotoolkit.org/browser/dijit/trunk/form/_AutoCompleterMixin.js?rev=24654#L556 both use this type of code

dojo.when(promise, function (result, error) {
    if (error) {
        // handle error
    }
    else {
        // handle result
    }
});

afaik, unless something is happening that is not "normal" for promises, this won't work in the error case. it should be

dojo.when(promise, function (result) {
    // handle result
}, function (error) {
    // handle error
});

[bill]

(In [25529]) fix dojo.when() calls, thanks neonstalwart, refs #12373 !strict

[bill]

(In [25531]) Better backwards compatibility: make ComboBox.store point to the original store passed in as an initialization parameter (even when the store implements the old dojo.data API), and make the selected item (ComboBox.item) a native item from that store. If ComboBox.store is the old dojo.data API, adds methods to make it act more like the new API.

Refs #12373 !strict

(In [25719]) fix typo, refs #12373 !strict

[ben hockey]

what is the plan for dijit.form.Select or more specifically dijit.form._FormSelectWidget? currently only dojo.data is supported.

[bill]

I'd like to get all the widgets supporting the new store API soon. Certainly by 2.0 (when we'll drop support for the old dojo.data API), but ideally for 1.8. No guarantees though.

Related to store conversion: should FilteringSelect? be a store Observer so that store changes that affect the query result set could be reflected in the FilteringSelect?'s validity (i.e. removing the FS's value item from the store should cause the FS to become invalid). Similar but unrelated to conversion, should FilteringSelect?.set('query') immediately result in a store.query() [again, to trigger a validation check]?

[bill]

should FilteringSelect be a store Observer so that store changes that affect the query result set could be reflected in the FilteringSelect's validity

We could do that, although it comes at the cost of more code, and no one has requested it until now so it doesn't seem like anyone needs that.

Similar but unrelated to conversion, should FilteringSelect.set('query') immediately result in a store.query() [again, to trigger a validation check]?

Yes, technically that should happen, resetting the query could affect the validity or change the selected item. Again though it's an edge case that requires more code and not sure if it's worth it.

Anyway, neither of these issues has anything to do with this ticket.

(In [25771]) Switch ComboBox? back so it passes in a string rather than a regex when talking to a store with the old dojo.data API. Seems better for backwards compatibility.

Refs #12373, #13416, #13880 !strict.

[bill]

(In [25934]) Allow dynamic update of ComboBox.store, refs #12373, fixes #13511 !strict

[bill]

In [26896]:

For better back-compat, when connecting to legacy store, make sure searchAttr is an actual String rather than a Regex with a toString() method. This was done for ComboBox in [25771] but I missed the other case of FilteringSelect's reverse lookup.

Also avoid (unnecessarily) adding a toString() method to a String.

The code duplication is unfortunate but it will go away in 2.0.

Fixes #14099, refs #12373 !strict.
