<a4j:outputPanel> produces javax.servlet.ServletException: duplicate Id for a component form:j_id6 -------------------------------------------------------------------------------------------------- Key: RF-5734 URL: https://jira.jboss.org/jira/browse/RF-5734 Project: RichFaces Issue Type: Bug Affects Versions: 3.3.0, 3.2.2 Environment: java 1.6.11, Glassfish V2, Windows XP Prof Reporter: Bjoern Sonntag we've found one bug in the a4j:outputPanel - tag... szenario : In our project we have severals subprojects which have 2 webpages with simple navigation rule. Side A leads to side B and you can get from side B to side A, but when we go from side B to side A we got an exception : javax.servlet.ServletException: duplicate Id for a component form:j_id6 We have following interesseting code in our jsps <a4j:outputPanel layout="none" id="mainContentPanel"> <!-- here are some widgets, like outputLabel, inputText, rich:calendar etc. --!> </a4j:outputPanel> which we use like a tag to render several widgets, or not. But when we replace the <a4j:outputPanel> with a <rich:panel> and navigate from side B to side A its works fine but our markup looks like a slap with a golf club. This behaviour is repeatable ! So we think there is a bug in the <a4j:outputPanel> or the Richfaces Framework have a problem with that. When you google for ""duplicate id" Richfaces a4j" you can see many many posting, that have <a4j:outputPanel> as common ground. with best regards Bjoern -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
