http://nagoya.apache.org/bugzilla/show_bug.cgi?id=21108 java.util.ConcurrentModificationException occurs in iterator ------- Additional Comments From [EMAIL PROTECTED] 2003-06-26 14:57 ------- The error occurs when I select an html:link on the labkitAdminForm (below) which then opens the labkitForm. Essentially, the labkitAdminForm displays a list of labkits to a user. The user then selects one of the labkits from the list to edit. The error occurs when the selected labkit is being opened. The jsp page is being run from JBoss-2.4.8_Tomcat-4.0.4 application/web server. The data is served by EJB. The ActionForm does not access the EJB directly, but uses a Proxy (A facade wrapping the EJB reference). -------------------------------------------------------------------------- struts-config.xml config for the Action/ActionForm being used: <action path="/labkitAdmin" type="com.globalknowledge.rlms.workflow.admin.resources.LabKitAdminAction" name="labkitAdminForm" scope="request" validate="false" parameter="method"> <forward name="labkitedit" path="/workflow/admin/resources/index.jsp" /> </action> <action path="/labkit" type="com.globalknowledge.rlms.model.labkit.LabKitAction" name="labkitForm" scope="request" validate="false" parameter="method"> <forward name="labkitedit" path="/workflow/admin/resources/createLabKit.jsp" /> <forward name="labkitcreate" path="/labkit.do?method=create" /> <forward name="labkitupdate" path="/labkit.do?method=update" /> <forward name="labkitsuccess" path="/labkitAdmin.do?method=index" /> <forward name="labkiteditext" path="/workflow/admin/resources/createLabKitExt.jsp" /> <forward name="labkitfailure" path="/labkitAdmin.do?method=index" /> <forward name="labkitcancel" path="/labkitAdmin.do?method=index" /> <forward name="labkitListCourses" path="/workflow/admin/resources/addCourse.jsp" /> <forward name="labkitUnassignCourse" path="/labkit.do?method=unassignCourse" /> </action> -------------------------------------------------------------- A segment of the labkit admin jsp looks like this: ..... <logic:notEqual name="course" property="labKitSize" value="0"> <tr> <th valign="center" align="center" width="15%"><bean:message key="label.resources.courses.labkits.edit"/>/<bean:message key="label.resources.courses.labkits.delete"/></th> <th valign="center" align="center" width="15%"><bean:message key="label.resources.courses.labkits.id"/></th> <th valign="center" align="center" width="15%"><bean:message key="label.resources.courses.labkits.name"/></th> <th valign="center" align="center" width="10%"><bean:message key="label.resources.courses.labkits.schedule"/></th> <th valign="center" align="center" width="10%"><bean:message key="label.resources.courses.labkits.reserve"/></th> <th valign="center" align="center" width="35%"><bean:message key="label.resources.courses.labkits.description"/></th> </tr> <logic:iterate id="labkitForm" name="course" property="labKits" type="com.globalknowledge.rlms.model.labkit.LabKitTextForm" > <tr> <td valign="center" align="center" width="15%" > <html:link forward="labkitedit" paramId="id" paramProperty="id" paramName="labkitForm">Edit</html:link>/<html:link forward="labkitremove" paramId="id" paramProperty="id" paramName="labkitForm">Delete</html:link> </td> <td valign="center" align="center" width="15%" > <bean:write name="labkitForm" property="id" /> </td> <td valign="center" align="center" width="15%" > <bean:write name="labkitForm" property="name" /> </td> ..... ------------------------------------------------------------------ A segment of the labkit jsp page looks like this: <html:html locale="true"> <bean:message key="label.labkit.heading" /> <body> <html:errors/> <html:form action="labkit.do?method=select"> <table border="0" width="100%" height="100%"> <tr> <td valign="center" align="left" width="10%"> <bean:message key="label.labkit.name" /><br><br> </td> <td valign="center" align="left" width="40%"> <html:text name="labkitForm" property="name" /><br><br> </td> <td valign="center" align="left" width="10%"> <bean:message key="label.labkit.type" /><br><br> </td> <td valign="center" align="left" width="40%"> <html:select name="labkitForm" property="selectedType" size="1" > <html:optionsCollection name="labkitForm" property="types" /> </html:select><br><br> </td> </tr> <tr> <td valign="center" align="left" colspan="4" width="100%"> <table border="0" width="100%" height="100%"> <tr> <td valign="top" align="left" width="10%"> <bean:message key="label.labkit.description" /><br><br> </td> <td valign="center" align="left" width="90%"> <html:textarea name="labkitForm" property="description" cols="64" rows="4" /><br><br> </td> </tr> </table> </td> </tr> --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
