Form Navigator Plugin Portlet in liferay 7 GA2 ?

[Ravi Shankar, modificado 7 Anos atrás.]

Hi guys,

I have created one sample form navigator portlet in liferay 7 GA2. Please see the below files.

/docroot/html/formnavi/view.jsp:

<%@ include file="/html/formnavi/init.jsp" %>
<%
String[] CATEGORY_NAMES = new String[]{"basic-information", "educations", "hobbies"};
String[] basic_information = new String[]{"profile", "contacts"};
String[] educations = new String[]{"university", "high_school"};
String[] hobbies = new String[]{"sports", "entertaimens"};
String[][] categorySections = {basic_information, educations, hobbies};
%>
<portlet:actionURL var="formAction" name="updateStudent" />
<aui:form action="<%=formAction%>" method="post" name="fm">
<liferay-ui:form-navigator
categoryNames="<%= CATEGORY_NAMES %>"
categorySections="<%= categorySections %>"
jspPath="/html/formnavi/subjsp/"
/>
</aui:form>

/docroot/html/formnavi/subjsp

contacts.jsp
enterinment.jsp
high_school.jsp
profile.jsp
sports.jsp
university.jsp

/docroot/html/formnavi/init.jsp:

<%@ taglib prefix="liferay-ui" uri="http://liferay.com/tld/ui" %>
<%@ taglib prefix="liferay-util" uri="http://liferay.com/tld/util" %>
<%@ taglib prefix="liferay-theme" uri="http://liferay.com/tld/theme" %>
<%@ taglib prefix="portlet" uri="http://java.sun.com/portlet" %>
<%-- <%@ taglib prefix="aui" uri="http://alloy.liferay.com/tld/aui" %> --%>
<portlet:defineObjects />
<liferay-theme:defineObjects />

/com/blogspot/chingovan/formnavi/FormNavi.java

package com.blogspot.chingovan.formnavi;
import javax.portlet.ActionRequest;
import javax.portlet.ActionResponse;
import com.liferay.portal.kernel.util.ParamUtil;
public class FormNavi extends com.liferay.portal.kernel.portlet.bridges.mvc.MVCPortlet {
public void updateStudent(ActionRequest request, ActionResponse response) {
String name = ParamUtil.getString(request, "name");
System.out.println("name: " + name);
int age = ParamUtil.getInteger(request, "age");
System.out.println("age: " + age);
boolean gender = ParamUtil.getBoolean(request, "gender");
System.out.println("gender: " + gender);
String address = ParamUtil.getString(request, "address");
System.out.println("address: " + address);
String telephone = ParamUtil.getString(request, "telephone");
System.out.println("telephone: " + telephone);
String homephone = ParamUtil.getString(request, "homephone");
System.out.println("homephone: " + homephone);
String universityName = ParamUtil.getString(request, "universityName");
System.out.println("universityName: " + universityName);
String universitySubject = ParamUtil.getString(request, "universitySubject");
System.out.println("universitySubject: " + universitySubject);
String highSchoolName = ParamUtil.getString(request, "highSchoolName");
System.out.println("highSchoolName: " + highSchoolName);
String favoriteSport = ParamUtil.getString(request, "favoriteSport");
System.out.println("favoriteSport: " + favoriteSport);
String favoriteMovie = ParamUtil.getString(request, "favoriteMovie");
System.out.println("favoriteMovie: " + favoriteMovie);
String favoriteSong = ParamUtil.getString(request, "favoriteSong");
System.out.println("favoriteSong: " + favoriteSong);
String favoriteBook = ParamUtil.getString(request, "favoriteBook");
System.out.println("favoriteBook: " + favoriteBook);
}
}

In this portlet I am facing problem with below tag:

<liferay-ui:form-navigator
categoryNames="<%= CATEGORY_NAMES %>"
categorySections="<%= categorySections %>"
jspPath="/html/formnavi/subjsp/"
/>

It throws the below error. see error log:
