T5: Recording custom validation errors onEvent(blur) on a form
field
Hi everyone,
Ok this is what i'm looking for: A user types in their desired username,
when the onBlur event happens on that input field (i.e. focus switches to
the next field), IF the name is taken i'd like to utilise the standard
tapestry validation error bubble, and display a message "User Name Taken".
This is my solution, which doesn't display the message at all:
Page Class (simplified):
@Component(id = "registerBasicForm")
private Form registerBasicForm;
@Component
private Zone registerBasicZone;
@Component(id = "registerbasic_userName")
@Mixins("t5components/OnEvent")
private TextField userNameField;
@OnEvent(component = "registerbasic_userName", value = "blur")
public Object onBlurEvent(String value) {
System.out.println("onBlurEvent() value: " + value);
//Hardcoded username for testing purposes
if(value.equals("iexist")) {
System.out.println("exists");
registerBasicForm.recordError(userNameField,"that name exists");
System.out.println("registerBasicForm.getHasErrors():"+registerBasicForm.getHasErrors());
}
return registerBasicZone;
}
public void onValidate() {
System.out.println("onValidate()");
}
public void onValidateForm() {
System.out.println("onValidateForm()");
}
public void onValidateFromUserName(){
System.out.println("onValidateFromUserName()");
}
public void onSubmit() {
System.out.println("onSubmit()");
}
public Object onSuccess() {
System.out.println("onSuccess()");
return registerBasicZone;
}
public Object onFailure() {
System.out.println("onFailure()");
return registerBasicZone;
}
public void onSubmitFromRegisterBasicForm() {
System.out.println("onSubmitFromRegisterBasicForm()");
}
TML:
<t:zone t:id="registerBasicZone" visible="true">
<t:form t:id="registerBasicForm" t:class="gForm" zone="registerBasicZone">
<t:label for="registerbasic_userName">User Name:</t:label>
<t:textfield t:id="registerbasic_userName" t:value="userName"
event="blur"/>
<br/>
<t:label for="registerbasic_password1">Password:</t:label>
<t:passwordfield t:id="registerbasic_password1" t:value="password1"/>
<br/>
<t:label for="registerbasic_password2">Repeat Password:</t:label>
<t:passwordfield t:id="registerbasic_password2" t:value="password2"/>
<br/>
<t:label for="registerbasic_email">Email:</t:label>
<t:textfield t:id="registerbasic_email" t:value="email"/>
<br/>
<t:label for="newsletter">Subscribe?</t:label>
<t:checkbox t:id="newsletter" t:value="newsletter"/>
<br/>
<t:label for="terms">Agree to terms ?</t:label>
<t:checkbox t:id="terms" t:value="terms"/>
<br/>
<input t:id="submit" t:type="Submit" t:value="submit" />
</t:form>
</t:zone>
I'm expecting to see the error bubble onBlur(), but is this a correct
assumption? I can't find much documentation on recordError, do the errors
get added to the form onValidate() maybe? Also is it correct behaviour to
return the zone from the onBlurEvent()? I'm quite new to tapestry forms and
zones.
This is my logging output:
onBlurEvent() value: iexist
exists
registerBasicForm.getHasErrors(): true
Any help on this matter would be much appreciated.

Sorry for the shameless bump, but I'd really appreciate some help on this.
