I've been taking a look to your code, and if I understand well, you mean to do what you implement in the RowAndColumnRelationshipsHtmlDataTable constructor, but within my setter method inside my backing bean, don't you?
2005/11/3, Mike Kienenberger <[EMAIL PROTECTED]>:
Enrique,
Try a different approach.
Put this code in your setPanelTabuladores() method. You don't need
to create a HtmlPanelTabbedPane because this component is already
created for you. All you need to do is create tabs and add them to
the table passed into the method. I think you should do this using
parent.getChildren().add(child) instead of child.setParent() as that's
how I've always seen it done in the past.
You can find a very old example I wrote of dynamically creating
components in a dataTable subclass as an attachment here. It might
be of help. If so, the most interesting class is
RowAndColumnRelationshipsHtmlDataTable as it does all of the creation
work.
