It should take iterator. I just wanted to point out that the component
will coerce an iterator, so you don't have to specify it. The more
important aspect of my reply has to do with item, which isn't of type
Iterator.

in tapestry component reference say that source can be Iterator,

Don't pass in "treeModel.iterator" for source, but just "treeModel".
Tapestry will coerce the object into an Iterator.
Again, have a look at the Foreach class and .jwc file to see what's
going on.

i think this isn't the problem
model must be type TreeModelItem and ongl:item is a
java.util.Iterator not a TreeModelItem
but i test it and it don't work for my example

Do you just want to say:
<div jwcid="@TreeItemView" model="ognl:item"/>
in your TreeItemView?
