Hi DarkStar, Just in case you weren't aware, where you see <entity_name> you should substitute the name of the entity you want, such as "Party". If you do a view source on the page in the browser, you might find that the td with a class of dark-grid was rendered before the error occurred. This would give you the value of the key variable.
The basic approach of using groovy to retrieve some data and populate a collection for use by freemarker is common. See for example https://fisheye6.atlassian.com/browse/ofbiz/trunk/applications/party/webapp/partymgr/WEB-INF/actions/party/ViewProfile.groovy?hb=true which is called from https://fisheye6.atlassian.com/browse/ofbiz/trunk/applications/party/widget/partymgr/PartyScreens.xml?hb=true#to67 Yes, Groovy is replacing beanshell and should be used for anything new.
