使用Struts2.3.16.1遇到如下错误，不能导入struts2-dojo-plugin-2.3.15.jar中的模版
严重: Template processing error: "Error reading included file template/~~~ajax/controlheader-core.ftl" Error reading included file template/~~~ajax/controlheader-core.ftl The problematic instruction: ---------- ==> include "/${parameters.templateDir}/${parameters.expandTheme}/controlheader-core.ftl" [on line 23, column 1 in template/xhtml/controlheader.ftl] in include "/${parameters.templateDir}/xhtml/controlheader.ftl" [on line 24, column 9 in template/ajax/controlheader.ftl] in include "/${parameters.templateDir}/ajax/controlheader.ftl" [on line 23, column 1 in template/ajax/datetimepicker.ftl] ---------- Java backtrace for programmers: ---------- freemarker.template.TemplateException: Error reading included file template/~~~ajax/controlheader-core.ftl
这是Struts2.3.16.1本身的问题，会在以后的版本中修复：https://issues.apache.org/jira/browse/WW-4254 ，在Struts2.3.15中没有这个问题。
