I had deployed a portlet on portal server, Now created user suppose "jboss"on portal server. Logged in as jboss user and clicked on EDIT button of my portlet window, On "save" it executes required code of my portlet application, but throws exception. Please find the stackTrace below. org.hibernate.NonUniqueResultException: query did not return a unique result: 2 at org.hibernate.impl.AbstractQueryImpl.uniqueElement(AbstractQueryImpl.java:765) at org.hibernate.impl.AbstractQueryImpl.uniqueResult(AbstractQueryImpl.java:756) at org.jboss.portal.core.impl.model.instance.InstanceImpl.invoke(InstanceImpl.java:249) at org.jboss.portal.core.command.RenderWindowCommand.execute(RenderWindowCommand.java:109) at org.jboss.portal.core.command.ControllerCommand.dispatch(ControllerCommand.java:84) at org.jboss.portal.common.invocation.Invocation.invokeNext(Invocation.java:141) at org.jboss.portal.core.aspects.controller.EventBroadcasterInterceptor.invoke(EventBroadcasterInterceptor.java:168) On checking database.script for hypersonic , found it creates 2 enteries for user "jboss", not sure why?
