Hi,

I've recently installed this and trying to use but I get errors in many places. To start with please see the below error while I click on "Forums" in the left pane on page jforum/admbase/login.page. Also can anyone please tell how to understand which page exactly is running. Is this developed in AJAX. I'm not much of techie guy but when I try to trace which page is been loaded I'm lost ..

Expression $category is undefined on line 21, column 66 in default/admin/forum_list.htm. The problematic instruction: ---------- ==> assignment: forums=repository.getCategory($category.id).getForums() [on line 21, column 25 in default/admin/forum_list.htm] ---------- Java backtrace for programmers: ---------- freemarker.core.InvalidReferenceException: Expression $category is undefined on line 21, column 66 in default/admin/forum_list.htm. at freemarker.core.TemplateObject.assertNonNull(TemplateObject.java:124) at freemarker.core.TemplateObject.invalidTypeException(TemplateObject.java:134) at freemarker.core.Dot._getAsTemplateModel(Dot.java:78) at freemarker.core.Expression.getAsTemplateModel(Expression.java:89) at freemarker.core.ListLiteral.getModelList(ListLiteral.java:119) at freemarker.core.MethodCall._getAsTemplateModel(MethodCall.java:89) at freemarker.core.Expression.getAsTemplateModel(Expression.java:89) at freemarker.core.Dot._getAsTemplateModel(Dot.java:74) at freemarker.core.Expression.getAsTemplateModel(Expression.java:89) at freemarker.core.MethodCall._getAsTemplateModel(MethodCall.java:86) at freemarker.core.Expression.getAsTemplateModel(Expression.java:89) at freemarker.core.Assignment.accept(Assignment.java:90) at freemarker.core.Environment.visit(Environment.java:196) at freemarker.core.MixedContent.accept(MixedContent.java:92) at freemarker.core.Environment.visit(Environment.java:196) at freemarker.core.ConditionalBlock.accept(ConditionalBlock.java:79) at freemarker.core.Environment.visit(Environment.java:196) at freemarker.core.IteratorBlock$Context.runLoop(IteratorBlock.java:160) at freemarker.core.Environment.visit(Environment.java:351) at freemarker.core.IteratorBlock.accept(IteratorBlock.java:95) at freemarker.core.Environment.visit(Environment.java:196) at freemarker.core.MixedContent.accept(MixedContent.java:92) at freemarker.core.Environment.visit(Environment.java:196) at freemarker.core.Environment.process(Environment.java:176) at freemarker.template.Template.process(Template.java:232) at net.jforum.JForum.processCommand(JForum.java:233) at net.jforum.JForum.service(JForum.java:200) at javax.servlet.http.HttpServlet.service(HttpServlet.java:803) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:269) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at net.jforum.util.legacy.clickstream.ClickstreamFilter.doFilter(ClickstreamFilter.java:59) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:215) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:174) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:117) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:108) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:174) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:874) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:665) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:528) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:81) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:689) at java.lang.Thread.run(Unknown Source)

There was a error in the code of page forum_list under default/admin/

There was a "$" before category.id in the following line, removing that solved the problem.

<#assign forums = repository.getCategory(category.id).getForums()/>
