ClassCastException: java.lang.String at org.jboss.seam.framework.Query.parseEjbql() ----------------------------------------------------------------------------------- Key: JBSEAM-3647 URL: https://jira.jboss.org/jira/browse/JBSEAM-3647 Project: Seam Issue Type: Bug Components: Framework Affects Versions: 2.1.0.GA Environment: Linux, JBoss 4.2.2 GA, Java 5 Reporter: Gabriel Goïc Assignee: Norman Richards Since I upgraded my web-app to Seam 2.1 GA from 2.0.2 SP1, I'm getting the same error on several different pages. It is displayed under two different exception stack trace patterns, shown below. My code didn't change, I have some *List classes that extend EntityQuery in a raw way and override "public String getEjbql()". First exception pattern: 2008-10-29 16:30:15,500 DEBUG [org.jboss.seam.core.Manager] No stored conversation (http-xxx) 2008-10-29 16:30:15,506 DEBUG [org.jboss.seam.core.Manager] Beginning
