//a page that needs an identity
public class ShowCollective extends PengBasePage {

//the login page
public class Start extends CommonPengBasePage {
@Inject

@Inject
private Messages messages;
@Component
private Form loginForm;
private String email;
private String password;
public String getEmail() {

public void setEmail(String email) {
this.email = email;
}
public String getPassword() {

public void setPassword(String password) {
this.password = password;
}
@OnEvent(component="doLogin")
public String handleLogin() {
if(loginForm.isValid()) {
PengUserDTO pengUser = pengUserService.login(email,
password);
if (pengUser == null)
{
loginForm.recordError(messages.get("login-error"));
} else {
setIdentity(pengUser);
return "ShowCollective";
}
} else {
log.info("Form is not valid...");
}
return null;
}
}
This is a subset of my proof-of-concept-project, showing the "bug".
Actually I have a question regarding the handleLogin() method in page Start.
I have a Submit component with id doLogin (maybe not a very clever
name...) and i use that component id in @OnEvent for the method
handleLogin.
When the login succeeds and I return "ShowCollective" tapestry says throws this;
java.lang.IllegalArgumentException
Event 'selected' from net.keso.ted.peng5.pages.Start:doLogin received
an event handler method return value of ShowCollective from
net.keso.ted.peng5.pages.Start.handleLogin(). This type of event does
not support return values from event handler methods.
So my question is, how am I supposed to redirect/reroute to a
different page after an event coming from a submit button?
thanks

Sounds like a bug to me. I have seen some oddities involving the user
of inner classes and fields that are removed (I believe it's actually
a Javassist bug) but this doesn't seem to fall into that. Any chance
of showing us the code?
