The clayForEach should handle maps but it uses the entrySet's iterator. So, your clay config's/templates would have to assume that the managed-bean-name object is a Map.Entry ([EMAIL PROTECTED]). It seemed like a good idea at the time but if you would rather assume the Map.Entry.getValue(), please create a bugzilla ticket for that one. > Hermod > Gary > -----Opprinnelig melding----- > Fra: Hermod Opstvedt [mailto:[EMAIL PROTECTED] > Sendt: 28. mars 2006 18:40 > Til: 'Struts Users Mailing List' > Emne: [Shale] ClayforEach and Maps > > Hi > > I am currently converting one of my websites from Struts to > Shale/Hibernate3/Spring.
