Custom components..... How my faces do this?

[Dudu <ed...@yahoo.com.br>]

I do a custom component inherited of UIData to do the SortableTable of
DojoToolkit with some ajax functions....
and when I try to add childrens on jsp mode the IDE accept it, but if I try
to add a component UIColumn as your children the IDE do not accept it. How
to do this comportment. I have looked at source  code of MyFaces in many
places: HtmlDataTable.java, UIColumn.java, on tld files and I did'nt found
where is the code responsable about this and how to do this.
Anyone has the answer?
Another question. Are there a way to add some UIColumns as children of my
component?

Thanks community
