Thanks Robert,
Here is more code. I think I am doing the right things, just that this
element has body as well as attribute and that is messing me up :-(
I have 5 classes (Row, Column, Rows, Colums, Report) all the methods are
getting called correctly.
Object Row has one attribute (colnum) and body (which I set to setData)
Once row is created (both attribute and body), I need to add that Row object
in to Object Rows, by addRows() call on Rows. The problem is, colnum gets
set, then it calls addRow (on Rows) and then setData on Row. When it calls
setData, the clonum info ir right. But since order is messed up it has
problems. BTW: columns part is working fine!
Thanks
Shailesh

there are probably a couple of difficulties here.
the first is that i don't see an object creation rule. you may need to
add a rule to create the row. (see documentation for more details on the
choices.)
the second is that you're going to need to think about the ordering of
your rules. again, take a look at the documentation for more details.
if this doesn't help then i'd suggest posting a longer code snippet: one
that people can run. it's generally easier to diagnose things that way.
