"Expression hasCodeBlock" exception after upgrade from 2.1.7b3 to 2.1.8

[Migrated From Jforum.net]

I've just upgrade JForum 2.1.7b3 to 2.1.8 using java 1.5 in tomcat 5.5. We create a custom war (via maven2) by overlaying a slightly modified version of the default template header.htm, style.css, and a couple of images. This along with our settings in SystemGlobals.properties is the only differences from the standard distribution. This overlay worked fine with 2.1.7b3. After upgrading to the 2.1.8 war version, we've run into the following problem.

After the upgrade I get the following exception from the main forum index:

Expression hasCodeBlock is undefined on line 16, column 6 in default/bottom.htm. The problematic instruction: ---------- ==> if hasCodeBlock [on line 16, column 1 in default/bottom.htm] in include "bottom.htm" [on line 189, column 1 in default/forum_list.htm] ---------- Java backtrace for programmers: ---------- freemarker.core.InvalidReferenceException: Expression hasCodeBlock is undefined on line 16, column 6 in default/bottom.htm. at freemarker.core.TemplateObject.assertNonNull(TemplateObject.java:124) at freemarker.core.Expression.isTrue(Expression.java:145) at freemarker.core.ConditionalBlock.accept(ConditionalBlock.java:77) 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.include(Environment.java:1375) at freemarker.core.Include.accept(Include.java:155) 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:210) 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:151) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:870) 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:685) at java.lang.Thread.run(Thread.java:595)

The appropriate page is shown in the result on top followed by the exception above followed by what appears to be the error page. It shows in a "Information" box the following:

An error has occurred.

For detailed error information, please see the HTML source code, and contact the forum Administrator.

Expression hasCodeBlock is undefined on line 16, column 6 in default/bottom.htm.

Searching the community shows little to indicate what the source of the problem is.

In help is greatly appreciated.

Thanks,
Skip

Aw shucks. Nevermind. I went back and did another dif between my header.htm modified from 2.1.7b3 and the new 2.1.8 header.htm. Looks like I missed merging some pieces from the file. I think updating that file should take care of this issue at least.
