Mathias Werlitz commented on MYFACES-603: ----------------------------------------- Maybe this is somehow related to MYFACES-580 ? > duplicate id exception > ---------------------- > > Key: MYFACES-603 > URL: http://issues.apache.org/jira/browse/MYFACES-603 > Project: MyFaces > Type: Bug > Components: General > Versions: 1.1.0 > Environment: Tomcat 5.5.9, JDK 1.4.2, Windows NT > Reporter: Boris Klug > Priority: Critical > > When reloading a page, I get the exception below. > I search the mailing list and someone suggested to assign a id by hand > to every component - which is much work and would clumber the jsf pages. > I manualy added an id to the component with the duplicate id and > redeployed the app - now I get the exception from another component. So > what changed from 1.0.9m9 to 1.1.0 related to this problem? > Another strange thing is that I get the following warning: > 2005-09-20 15:06:39,481 INFO [/XXX]: WARNING: Component _id12 just got > an automatic id, because there was no id assigned yet. If this component > was created dynamically (i.e. not by a JSP tag) you should assign it an > explicit static id or assign it the id you get from the createUniqueId > from the current UIViewRoot component right after creation! > Everything went away after I rearragned the components like this: > Original: > <f:view> > .. jscookmenu > ... dataTable with command links > <h:form> > ... more dataTable with more command links > </h:form> > </f:view> > Now without problems: > <f:view> > ... jscookmenu > <h:form> > ... dataTable with command links > ... more dataTable with more command links > </h:form> > /f:view> > === Thrown exception ==== > 2005-09-20 15:06:47,753 ERROR [jsp]: Servlet.service() for servlet jsp threw > exception > javax.faces.FacesException: cannot add component with id '_id21' and path : > {Component-Path : [Class: > javax.faces.component.html.HtmlInputText,Id: _id21]} to its parent component. > This might be a problem due to duplicate ids. > at javax.faces.webapp.UIComponentTag.findComponent(UIComponentTag.java:401) > at javax.faces.webapp.UIComponentTag.doStartTag(UIComponentTag.java:219) > at > org.apache.jsp.templates.generic_jsp._jspx_meth_h_inputText_1(org.apache.jsp.templates.generic_jsp:1642) > at > org.apache.jsp.templates.generic_jsp._jspx_meth_h_panelGrid_4(org.apache.jsp.templates.generic_jsp:1598) > at > org.apache.jsp.templates.generic_jsp._jspService(org.apache.jsp.templates.generic_jsp:636) > at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97) > at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) > at > org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:322) > at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:291) > at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:241) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
