The error message is "optGroupInternalListUiBean.parameters is undefined" I had a quick look at the source of Struts2 and tag template, In [template/simple/optgroup.ftl]: line 23: <#if parameters.optGroupInternalListUiBeanList??>line 24: <#assign optGroupInternalListUiBeans=parameters.optGroupInternalListUiBeanList />line 25: <#list optGroupInternalListUiBeans as optGroupInternalListUiBean>line 26: <optgroup line 27: <#if optGroupInternalListUiBean.parameters.label??> error occurred in line 27, and the [optGroupInternalListUiBean] should be an instance of org.apache.struts2.components.ListUIBean,which inherit from org.apache.struts2.components.Component,and the method [getParameters] of [Component] should return a map, which should be never null.So, I think this error should not occur. The source version I have read is [struts2-core-2.2.3.jar],maybe you need upgrade to the latest version,and see if the error happen.
