dojo.widget.manager.getWidgetById() fails because the widget has not
been created yet. Manually adding an element to the DOM with the
"dojoType" attribute does not automically force DOJO to add that
element to the current list of widgets. The reason it is added
automatically when you have it coded into the HTML is because DOJO
parses the DOM onload, looking to add any widgets that it finds. Try
this:
Make sure the DOM element you are creating has it's ID set (in this
case i'll use 'firstTree')
dojo.widget.createWidget('firstTree');
This will tell DOJO to locate this DOM element and initialize it as a
widget. Now this should work:
dojo.widget.byId('firstTree');
This is short-hand notation for
dojo.widget.manager.getWidgetById('firstTree')
