id already exists error when using span="all" attribute





------- Additional Comments From [EMAIL PROTECTED]  2002-04-17 18:23 -------
As far as I have been able to tell, this is due to FOP having to 
reconsider how it is laying out the elements on the page.  It starts
filling up one column, then encounters the span="all" block so it has
to rebalance what came before.  It rolls back the layout, but leaves
any id registered so far still registered.

The solution is to make sure that ids are unregistered after a rollback.

The attached patch fixes the problem when the id that supposedly exists
belongs to a <fo:block>.  A better solution would fix the problem for
all the objects that call IDReferences().createID().  The patch was
created against version 0.20.3
