    1) I have deployed Audience Targeting application(version 1.1.2), downloaded from Marketplace, into vanilla Liferay 6.2-ga6 on Tomcat 7.0.62. 2) Then went to Site Configuration and clicked on Audience Targeting menu point. 3) Clicked on "Add User Segment" Result: The form's fields are not editable on the page. It is still possible to drag'n'drop rules, but there is no chance to edit Title, Description and fields in drag'n'dropped boxes. In logs error has appeared - {code} ERROR [http-bio-8080-exec-234][IncludeTag:129] Current URL /group/control_panel/manage?p_p_id=ctadmin_WAR_contenttargetingweb&p_p_lifecycle=0&p_p_state=maximized&p_p_mode=view&doAsGroupId=10184&refererPlid=28501&controlPanelCategory=current_site.configuration&_ctadmin_WAR_contenttargetingweb_redirect=http%3A%2F%2Flocalhost%3A8080%2Fgroup%2Fcontrol_panel%2Fmanage%3Fp_p_id%3Dctadmin_WAR_contenttargetingweb%26p_p_lifecycle%3D0%26p_p_state%3Dmaximized%26p_p_mode%3Dview%26doAsGroupId%3D10184%26refererPlid%3D28501%26controlPanelCategory%3Dcurrent_site.configuration%26_ctadmin_WAR_contenttargetingweb_tabs1%3Duser-segments%26_ctadmin_WAR_contenttargetingweb_mvcPath%3Dhtml%252Fcontent_targeting%252Fview.ftl&_ctadmin_WAR_contenttargetingweb_mvcPath=html%2Fcontent_targeting%2Fedit_user_segment.ftl generates exception: java.lang.AbstractMethodError java.lang.AbstractMethodError at org.apache.jsp.html.taglib.aui.form.end_jsp._jspService(end_jsp.java:805) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70) at javax.servlet.http.HttpServlet.service(HttpServlet.java:731) at com.liferay.portal.servlet.DirectRequestDispatcher.include(DirectRequestDispatcher.java:57) at com.liferay.portal.servlet.ClassLoaderRequestDispatcherWrapper.doDispatch(ClassLoaderRequestDispatcherWrapper.java:78) at com.liferay.portal.servlet.ClassLoaderRequestDispatcherWrapper.include(ClassLoaderRequestDispatcherWrapper.java:53) at com.liferay.taglib.util.IncludeTag.include(IncludeTag.java:295) at com.liferay.taglib.util.IncludeTag.doInclude(IncludeTag.java:192) at com.liferay.taglib.util.IncludeTag.doEndTag(IncludeTag.java:83) at freemarker.ext.jsp.TagTransformModel$TagWriter.endEvaluation(TagTransformModel.java:430) at freemarker.ext.jsp.TagTransformModel$TagWriter.afterBody(TagTransformModel.java:417) at freemarker.core.Environment.visit(Environment.java:312) at freemarker.core.UnifiedCall.accept(UnifiedCall.java:130) at freemarker.core.Environment.visit(Environment.java:221) at freemarker.core.MixedContent.accept(MixedContent.java:92) at freemarker.core.Environment.visit(Environment.java:221) at freemarker.core.Environment.process(Environment.java:199) at freemarker.template.Template.process(Template.java:237) at com.liferay.portal.freemarker.FreeMarkerTemplate.processTemplate(FreeMarkerTemplate.java:122) at com.liferay.portal.template.AbstractTemplate.processTemplate(AbstractTemplate.java:108) {code}
