I also get this error after upgrading to 1.0 from 0.9.
None of my code has changed during the upgrade.
I too get this error for a LayoutContainer, in particular, the subContainerWidget node of a custom widget.
Wierdly, if I remove the id html attribute from the layoutContainer in question and fall back to dojo's autonaming (LayoutContainer_x) then I still get the same error.
I think that this probably has to do with the changes in programatic widget construction.
Currently, I have a method to add a tab to a tab container:

myNamespace.addTab = function( tab, widget ) {
    console.debug( " : addTab" );

    var tmp = document.createElement('div');
    var cp = new dijit.layout.ContentPane( tab, tmp );
    myTabStrip.addChild( cp );
    cp.setContent( widget.domNode );    
    dojo.addClass( cp.domNode, "noOverflow" );
}

I get the error mentioned about ID clashes on the construction of the ContentPane.
In 0.9 this was the only way to programatically add a tab. Should this be performed differntly in 1.0, e.g:

myNamespace.addTab = function( tab, widget ) {
    console.debug( " : addTab" );

    var cp = new dijit.layout.ContentPane( {"id": "tempID" }, tmp );
    myTabStrip.addChild( cp );
    cp.setContent( widget.domNode );    
    dojo.addClass( cp.domNode, "noOverflow" );
}

the origin of my problem was in my ...

I've got a loader on my page:

function hideLoader(){
var loader = dojo.byId('loader');
dojo.fadeOut({ node: loader, duration:500, onEnd: function(){
loader.style.display = "none";
}}).play();
}

dojo.addOnLoad(function() {
var start = new Date().getTime();
dojo.parser.parse(dojo.byId('layout'));
dojo.byId('loaderInner').innerHTML += " OK !";
setTimeout("hideLoader()",250);
});

I got the error......
and if I comment the line: dojo.parser.parse(dojo.byId('layout')); It works :s
Maybe we've have to look around the dojo parser !!!

It could be caused by you doing setContent(widget.domNode) this clones the widget.domNode node which *may* contain the widgetId attribute and then attempts to parse it...if you are creating a TabContainer and inserting a widget into it... depending on what it is, you can usually use that widget as a direct child of the TabContainer (just asign it a title attribute so it gets a tab name) instead of wrapping it in a ContentPane (Adding extra overhead and complexity)

hi,
using dojo 1.0 i'm trying to build a standard application layout :

	
top
	

		 Question?
			menu1
			menu2
	


	
main content

In two words : a header, a left menu and a main content. The goal is to call external php files and includes them in the main content pane.

I've searched many hours and i stay troubled...

1) Why the "setUrl" function return always "dojo.byId("centre").setUrl is not a function" for example by using this piece of code (which is in the head section of my page):

function open_link(){

	dojo.byId("centre").setUrl('admin/user.php');
}

?
Do I have missed importing something ?

dojo.require("dijit.layout.ContentPane");
		dojo.require("dijit.layout.LayoutContainer");
		dojo.require("dijit.form.Button");
		dojo.require("dijit.Dialog");
		dojo.require("dijit.form.TextBox");
		dojo.require("dijit.form.FilteringSelect");
		dojo.require("dojo.parser");

2) The only way i've found making it working is:

function open_link(){
          
             dijit.byId("centre").setHref('admin/user.php')

}

but when clicking for the second time the link that fire this function, the console gives me "Couldn't create widgets in centre from admin/user.php Error: Tried to register widget with id==my_widget but that id is already registered"

I've noticed that deleting the id of the concerned widget fixes the error, but what if i want to target it later ?

Thanks a lot (and sorry for my bad english...)

Just find out another reason for this error:
If your element is defined with "dojotype" not "dojoType", and this happened even in dojo examples such as in comboxo and checkbox. you got such errors.

It could be solved by replacing "dojotype" with "dojoType".

It has broken all my pages which were working perfectly in Dojo 0.9
Is any fix for it coming asap ?

Hi,
I have the same problem, and I believe that it comes from parsing the same page twice.
I need to do this since I modify the page code dynamically.
I hope to get around this problem by parsing only selected Elements or by creating widgets programatically,
but of course this error is not nice.

Well I had it all throughout my application, as all things are created on fly,
and then I need to ir again and again
Unless this error is fixed, am not sure I can go ahead and redesing everything.

There should atleats be a way of unregistering that id if it is the cause of problem

When I click on a node in a tree, I am using dojo.xhrGet to replace a div with more code that needs parsing.
When I click on another, I need to parse it again.
I am getting the same error:
Error: Tried to register widget with id==userForm but that id is already registered

In my use case, I need to parse it again, because I replaced the content.
How do I unregister previous content, or make it so I don't care if I get a duplicate? (exception handler?) or have a flag to ignore duplicates?

// load the template
        dojo.xhrGet( 
        {    
            url: "user.html",
            handleAs: "text",
            timeout: 5000, // Time in milliseconds
            load: function(response, ioArgs) 
            { // successful response.
                var detailsPane = dojo.byId("detailsPane");
                detailsPane.innerHTML = response; 
                
                dojo.parser.parse(detailsPane); // to make dijits real
                
                // fill in the data
                dijit.byId('userForm').setValues(person);
                       
                return response;
            },
            error: function(response, ioArgs) 
            {
                console.error("HTTP status code: ", ioArgs.xhr.status);
                return response;
            }
          }
       );

hi,
before parse new content you must destroy old widget.

see destroyRecursive function of widget.

Or using destroy function (something like this):

dojo.query('[widgetId]', dojo.byId('divId')).forEach(function(w){w.destroy();});

This is the error i get when i try your solution FraFa.

So then, the problem stay the same.
Any solutions?

I was struggling with this for a while too.... try the following:

dojo.forEach(
  dojo.query('[widgetId]', document.getElementById(elementId)),
    function(widget) {
      // For some reason I can't access widget.widgetid; trim the "widget_" prefix off of the id
      var widgetId=widget.id.substring(7);
      if (dijit.byId(widgetId)) {
        dijit.byId(widgetId).destroy();
      }
    }
);

(elementId is the ID for the DOM node which contains the widgets I want to delete)

Martin

I ran into the same issue and fixed it by explicitly destroying everything before setContent. But then the hide function in Dialog.js was giving me problems on subsequent refreshes. For some reason this.domNode and this.bgIframe were undefined. I added checks in and now everything is working. Will the main problem with setContent and dialogs be fixed in 1.1 and anyone have any idea when 1.1 will be out?

hide: function(){
   if (this.domNode){
      this.domNode.style.display = "none";
   }
   if(this.bgIframe && this.bgIframe.iframe){
      this.bgIframe.iframe.style.display = "none";
   }
   this.disconnect(this._resizeHandler);
}

I'm having the xhr problem where there can be very many different element id:s that I may want to destroy. Can I dojo.query() for all dijit.form.DateTextBox and have them destroyed?

Hi all,

With Dojo 1.0.1 I've tried to use attribute datePattern for widget DateTextBox to format date as "dd/MM/yyyy" but it doesn't work. However, if I use constraints attribute as:
constraints="{datePattern: 'dd/MM/yyyy'}"
Works perfectly.

Is this a known bug ?

Another info: is possible to use attribute selector to choose time from the popup calendar of the DateTextBox ?

Thanks !

I have the same problem with dijit.Dialog

I am creating an innerHTML in the dialog and when I open that dialog a second time it gives me this error of "tried to register widget with id==xxxx".

I am using Dojo 1.1.0

This is my javascript

any help would be great.

thanks.

You probably have a couple of options:

1. dijit.byId('editPOCDialog').destroy() before creating the dialog again.
2. Create the dialog once and just replace its contents as needed.

I am using dojox Grid which is created programmatically. Now I need to refresh the grid on an action in another grid. somehow once I destroy the grid and then try to render the grid again I dont see the grid data (somehow the div grid container is removed from generated html) Here is my relevant code. Would appreciate any suggestions.

if(grid){
        			console.info('Grid will be destroyed and recreated !');
	        		grid.destroy();
	        		
            		grid=null;
	     		 }	 
	     		     
				//dojo.byId("existingGrid") = "";	     	
				//var gridDiv=document.createElement("div");
				//dojo.byId("existingGrid").appendChild(gridDiv);	            

	            grid = new dojox.Grid({ 
	                    model: usersModel, 
	                    structure: layout,
	                    onRowClick: areaLinkClicked
	            }, dojo.byId("existingGrid"));
	           
                                //grid.startup();
				//grid.render();
				//grid.update();

Can i modify it like this?

add:function(_1){
if(this._hash[_1.id]){
throw new Error("Tried to register widget with id=="+_1.id+" but that id is already registered");
}
this._hash[_1.id]=_1;
}
------〉
add:function(_1){
if(!this._hash[_1.id]){
//throw new Error("Tried to register widget with id=="+_1.id+" but that id is already registered");
this._hash[_1.id]=_1;
}
}
