Schulte Marcus,
I see what you mean... I altered my class to look like this and I changed the
HTML form. How does Tapestry know that the this tag should go into my
LoginComponent and execute the doLogin method without having it fully defined?
Anyway I got it to work with your help and the others but it seems strange.
<form jwcid="@Form"
listener="ognl:listeners.doLogin">
code changes:
-------------------
package com.entercite.finance.model.abstrt;
import com.entercite.finance.model.Login;
import org.apache.tapestry.IRequestCycle;
import org.apache.tapestry.html.BasePage;
public abstract class LoginComponent extends BasePage {
Login login = new Login();
public abstract void setMessage(String message);
public LoginComponent() { }
public Login getLogin(){ return this.login; };
public void setLogin(Login login){ this.login = login; };
public void setUserName(String userName){
this.getLogin().setUserName(userName); }
public String getUserName(){ return this.getLogin().getUserName(); }
public void setPassword(String password){
this.getLogin().setPassword(password); }
public String getPassword(){ return this.getLogin().getPassword(); }
public void doLogin(IRequestCycle cycle) {
String u = this.getLogin().getUserName();
String p = this.getLogin().getPassword();
if(isValidLogin(u,p) ) {
System.out.println("push to main");
cycle.activate("Main");
}
setMessage("Invalid user name or password.");
}
private boolean isValidLogin(String userName, String password) {
return "tapestry".equalsIgnoreCase(userName);
}
}
