Hi In 5.1.0.6 a parameter zone was added to Select. So in your case both Select component and mixin ZoneUpdater have 'zone' as parameter.In tapestry, if both component and mixin have the same parameter name, the parameter is assigned to the component and mixin does not get the parameter.
As ZoneUpdater does not get any value for 'zone' and 'zone' parameter is required , it complains. You can specify the parameter for zoneupdater as zoneupdater.zone='whatever' http://tapestry.apache.org/component-mixins.html regards Taha On Thu, Apr 14, 2011 at 8:42 PM, Dmitriy Vsekhvalnov <dvsekhval...@gmail.com > wrote: > Hi all, > just upgraded application to 5.1.0.8-SNAPSHOT, and got weird error for > components that includes ZoneUpdater ( > http://tinybits.blogspot.com/2010/03/new-and-better-zoneupdater.html) > > org.apache.tapestry5.ioc.internal.util.TapestryException: Parameter(s) > 'ZoneUpdater.zone' are required for > org.apache.tapestry5.corelib.components.Select, but have not been bound. > > But it bound :) If i change parameter definition to: > > @Parameter(defaultPrefix = BindingConstants.LITERAL, required = false) > private String zone; > > > it works perfectly. > > Is it something known (5.1.0.5 was working as expected) ? >
