dojo1.8 - tried to register but . . . already registered - building select widget - dojo

Question

Hi I had a trouble figuring out where select's id is registered at attempted once more.
Possible causes:-
1) ParseOnload and Parser.parse() on the same page
2) Giving the same id to another new select
3) Registering the same select with new id
I could not figure what cause the select to registered twice.

<div id='main_bContainer' data-dojo-type='dijit/layout/BorderContainer' data-dojo-props='design:"sidebar"'>
<div id='paneA' class='cP_Left' data-dojo-type='dijit/layout/ContentPane' data-dojo-props='region:"left"'>
<div id='surfaceElement1' style='border:1px solid #ccc; margin-bottom:5px; width:317px; height:55px;'><!--these dimensions here in this line override the dimensions as set by createSurface function-->
<div id='node_meterSelect'></div>
</div>
<div id='surfaceElement2' style='border:1px solid #ccc; width:317px; height:200px;'><!--these dimensions here in this line override the dimensions as set by createSurface function-->
<div id='node_cardSelect'></div>
</div>
</div>
<div id='paneB' class='cP_Right' data-dojo-type='dijit/layout/ContentPane'data-dojo-props='region:"center"'>
<!--<div id='surfaceElement3' style='border:1px solid #ccc;'> <!--width:520px; height:400px;'><!--it's the size-->
<!--</div>-->
</div>

var meter_Select = new Select
({store:memoStore1,
style:{width:'140px'},
}, "node_meterSelect");
meter_Select.startup();
on(meter_Select, 'change', function(evt)
{
console.debug('Selected Card = '+ meter_Select.value);
request.post('listofcards.php',{data:{cardX : meter_Select.value},
handleAs:"json"}).then(function(response)
...
...
The error is "
Error: Tried to register widget with id==node_meterSelect but that id is already registered"
What could be the problem? please advise.. Thanks in advance.

Answer 1

i found your solution. You do not map all the require values to the right variables ! So registry and combobox are not mapped right ! you map "combobox" on "on".
Take a look at this jsfiddle:

Your function head with missing parameters:
function (parser, ready, dom, domConstruct, gfx, declare,
_WidgetBase, Memory, Select, ObjectStore, request, on)
After correction:
function (parser, ready, dom, domConstruct, gfx, declare,
_WidgetBase, Memory, Select, ObjectStore, request,box,registry, on)
So i had to add box & registry and now everything should work fine.

Here is a working jsfiddle based on your code:

Maybe you used the id somewhere else in your code ?
require(["dijit/form/Select",
"dojo/data/ObjectStore",
"dojo/store/Memory","dojo/domReady!"
], function(Select, ObjectStore, Memory){
var store1 = new Memory({
data: [
{ id: "foo", label: "Foo" },
{ id: "bar", label: "Bar" }
]
});
var os = new ObjectStore({ objectStore: store1 });
var meter_Select = new Select
({store:os,
style:{width:'140px'},
}, "node_meterSelect");
meter_Select.startup();
})
