[CLOSED] grid issue when add diferent class to listStore
in this package com.extjs.gxt.samples.resources.client.model create this class
Customer1.java
Customer2.javaCode:package com.extjs.gxt.samples.resources.client.model; public class Customer1 extends Customer { public Customer1(String name, String email, int age) { setName(name); setEmail(email); setAge(age); } }
Customer3.javaCode:package com.extjs.gxt.samples.resources.client.model; public class Customer2 extends Customer { public Customer2(String name, String email, int age) { setName(name); setEmail(email); setAge(age); } }
in the class ExampleServiceImpl that is in com.extjs.gxt.samples.server change the method getCustomers() toCode:package com.extjs.gxt.samples.resources.client.model; public class Customer3 extends Customer { public Customer3(String name, String email, int age) { setName(name); setEmail(email); setAge(age); } }
when you call the tab "Bean Model Grid" in explorer return this errorCode:public List<Customer> getCustomers() { List<Customer> customers = new ArrayList<Customer>(); customers.add(new Customer1("Darrell", "[email protected]", 1)); customers.add(new Customer2("Maro", "[email protected]", 2)); customers.add(new Customer2("Alec", "[email protected]", 3)); customers.add(new Customer3("Lia", "[email protected]", 4)); return customers; }
