[Laszlo-user] Data Manipulation Confusion

I've been working on a data related problem for the last few days which
really has me confused. I must be missing something. I'm trying to do
something very simple. I have two XML datasets:
<item name="foo" address="bar"/>
<item name="" address=""/>
I have a simple editor which is bound to ds1 with a datapath like this:
The user can change things in the editor and save them. They can also
select 'New' to start again. What I've been trying to figure out is how
to clone the item element from my template dataset and use it to replace
the edited value found in ds1. Looking in the documentation I can see how
I could add the template item to ds1 and then delete the original node
from ds1 using the addNodeFromPointer, but then if the user edits the
values, the values in my template are disturbed. What I want to do is add
a deep clone of my template node to the ds1 dataset so that if/when it
gets edited, my template remains unaffected.
What am I missing? I can find the node I'm interested in by doing
xpathQueries. I can clone the LzDataElement returned from the
xpathQuery. Once I have that, I don't see how I can add that element as a
node in my ds1 dataset.
Any help on this would be greatly appreciated.
