dojo dnd change the type of the dragged element - dojo

Question

I am using Dojo 1.8.3
I want to develop a Customizable Form using dnd. I have a list of form elements in the left dojo/dnd/Source and the container in the right dojo/dnd/Target which is supposed to generate dijits when I drop on it.
<div class="normal" style="width: 99%; height: 99%;" data-dojo-type="dijit/layout/BorderContainer"
data-dojo-props="design:'sidebar', gutters: true, liveSplitters: true">
<div data-dojo-type="dijit/layout/ContentPane" class="normal" style="width: 30%; height: 80%;"
data-dojo-props="splitter: true, region: 'left'">
<div data-dojo-type="dojo/dnd/Source" data-dojo-id="form_tools" id="form_tools" data-dojo-props="copyOnly: true"
class="container" style="width:99%;">
<div class="dojoDndItem" dndtype="heading">Heading</div>
<div class="dojoDndItem" dndtype="textbox">Text Box</div>
...
</div>
</div>
<div data-dojo-type="dijit/layout/ContentPane" class="normal" id="form_container"
style="width: 68%; height: 80%;" data-dojo-props="splitter: true, region: 'center'">
<div data-dojo-type="dojo/dnd/Target" data-dojo-id="form_items" id="form_items" class="container" style="height: 80%;" accept="heading,textbox">
<script type="dojo/on" event="DndDrop"> form.transform_item(arguments[0], arguments[1], arguments[2], arguments[3]);//source, nodes, copy, target </script> </div>
</div>
</div>
In my js function transform_item, I am doing this:
this.transform_item = function(){
var dragged_items = arguments[3].selection;
form_items.forInSelectedItems(function(item, id, map){
var dnditem = dojo.byId(id);
switch(item.type[0]){
case "textbox":
var textbox = new dijit.form.TextBox({
name: "textbox",
value: "This is a TextBox"
}, "textbox_text");
// HERE IS WHERE I SHOULD INSERT THE CODE FOR GENERATING A TEXTBOX
require(['dojo/parser'], function(parser){
parser.parse('textbox_text');
});
break;
}
});
}
At this point I'm getting an error when I drop over the Target :
dojo/parser::parse() error
TypeError: root is null
var node = root.firstChild;
How can I make Dojo generate, for example a dijit.form.TextBox when I drag an "textbox" dndtype?

Answer 1

Solved: I have just inserted the textbox in the wrong parent, textbox_text does not exist.So No need of parse();
