I'm under a restriction to have an xhtml compliant design time page.
Therefore I have a single empty div as a placeholder for the dialog control I want to create.
I need tab containers inside this dialog and i need to create it all within javascript and get it in that div.
I have tried many different combinations of addChild and appendChild but my tab container never shows content. Sometimes it appears as a tiny box other time its a bar across the top of the area in firefox.

Has anyone gotten this done or seen this issue?
Any help would be greatly appreciated.

I can't find this answer in the Book of Dojo. I'm nesting layout containers inside layout containers. When should I call addChild() to add it to the parent container?

Should I add them as I create them?....

...or should I create all of them first, and then add them together at the end?

var bc1 = new dijit.layout.BorderContainer(...);
