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? regards, jephte clain jclain@univ-reunion.fr
