dijit.form.FilteringSelect, setValue & onChange

[guest]

Hello, I use the setValue function to select a default value in the FilteringSelect? dijit, but this function seems to not call the onChange function. Is this the correct behaviour ? Thx in advance. Kilroy

This seems to work for me. Can you append a testcase? The nightly build has an example of a setDisplayedValue() that triggers onChange. ​http://archive.dojotoolkit.org/nightly/dojotoolkit/dijit/tests/form/test_FilteringSelect.html The first select box has a button to set the value to Kentucky and you can see the input box to the right change to KY via onChange.
You can modify this test to call
setValue('KY')
instead of
setDisplayedValue('Kentucky')
to verify that this works as well.

The difference with the example is that I create my dijit programaticaly.

var w = dojo.byId('actionsAvalon');
if (w)
{
	var dfltValue = w.value;
	w = new dijit.form.FilteringSelect
	(
		{
		    name          : w.name
		  , type          : w.type
		  , disabled      : w.disabled
		  , autocomplete  : true
		  , required      : true
		  , store         : new dojo.data.ItemFileReadStore({ url: '/avalon/getActions' })
		  , onChange      : function(action) {_this.onChangeAction(action); }
		  , searchAttr    : 'label'
		  , invalidMessage: _this._strings['invalid_action']
		  , promptMessage : _this._strings['missing_action']
		}
		, w
	);
	w.setValue(dfltValue);
	/* [BUG] Ticket #4870: setValue don't call onChange */
	_this.onChangeAction(dfltValue);
}

Even If i set the value in the constructor.

Maybe there's a race condition if you call setValue() before the store has loaded the data? Try attaching the setValue() call to a button, or running after a delay, to see if that works.

Also, you can (and should) attach testcases using the "attach file" button.

BTW, you can replace {{ {function(action) {_this.onChangeAction(action); } }}} with dojo.hitch(_this, "_onChangeAction") . It's just a little shorter to type.

I've changed :

w.setValue(dfltValue);
/* [BUG] Ticket #4870: setValue n'appelle pas onChange */
_this.onChangeAction(dfltValue);

with :

setTimeout
(
    function(){dijit.byId('actionsAvalon').setValue(dfltValue);}
  , 15000
);

but setValue don't call onChange.

I attached a programmatic example that works perfectly. Please try to recreate, starting with this example and tweak until it fails. Also, make sure you are using the latest trunk. I tested with [11354] with FF2 and IE6 on WinXP.
