Guys & Girls
After i've half got over my webservice problems i've decided to tackle
another issue i have. Right here goes - I have a sign up page which contains
a text field with <a4j:support> on it. This works fine - calls the method in
the backing bean fine - however i'm unsure how to code the next bit. The
'onChange' javascript event is fired and the username entered is passed to a
validator to see if it is available. This method returns true / false. I
want to be able to map this up so that redCross.gif is displayed next to the
field if the service method returns false. How do i go about doing this?
I'm guessing i cant just return a boolean from the ajax method called - it
has to be in a standard response? but how? Here is what i have already:
----------------------------------
signupPage.xhtml
....
<h:inputText
value="#{signupForm.user.username}" id="username" required="true" >
<a4j:support event="onchange"
action="#{signupForm.validateUsername}"/>
<v:commonsValidator type="required"
arg="Username"/>
</h:inputText>
....
signupForm.java
....
public boolean validateUsername(){
return
accountManagementService.isUsernameAvailable(user.getUsername());
}
Dont think i can return a boolean can i?
Many Thanks
Sion
