[Zope-dev] how to iterate on a list of DataSkins?

[Jephte CLAIN]

hello,

I have a custom Rack which have a searchResults:

-----8<-----
def searchResults(self, **kw):
	sqlresults = self.sql_search(kw)
	return map(
		lambda r, self=self: self.getItem(r.key), 
		sqlresults
	)
-----8<-----

The sql query give me a list of keys to be looked up in the ZODB. I have
got an AttributeProvider on the rack which get the other attributes from
the SQL table.
However, when I try to use the results from DTML inside the specialist:

<dtml-in "searchResults()">
<dtml-var sqlvalue>
</dtml-in>

This does not work. It throws an exception (sqlvalue not found)
But:

<dtml-var "searchResults()[0].sqlvalue">

*does* work. Why the DataSkin seems no to be pushed on the variable
stack in the first case???

any ideas?
