Hello!
I am trying to use ajax4jsf and MyFaces. So far everything looks great
except for the messages that I cannot show.
Here is my jsp:
<h:inputText id="newEmail"
value="#{mbUserBean.newEmail}" styleClass="requiredInput" required="true"
size="40"/>
<a4j:commandLink reRender="content" value="Add user"
actionListener="#{mbUserBean.addUser}" styleClass="commonLink"/>
<a4j:outputPanel ajaxRendered="true">
<h:message for="newEmail"
errorClass="errorText"/>
<h:messages />
</a4j:outputPanel>
(According to "The AJAX framework should not append or delete, but only
replaces elements on the page. For successful updates, an element with the
same ID as in the response must exist in the page. If you want append any
code to a page, put in a placeholder for it (any empty element). For the
same reason, we recommend placing messages in the AjaxOutput component
(since no messages is also a message)." in
https://ajax4jsf.dev.java.net/nonav/documentation/ajax-documentation/developerGuide.html)
In the UserBean:
public void addUser(ActionEvent evt) {
try {
UserService.createUser(getNewEmail());
newEmail = "";
} catch (DuplicateEmailException ex) {
FacesMessage msg = new FacesMessage(FacesMessage.SEVERITY_ERROR,
"User already exists with this email", "");
FacesContext.getCurrentInstance().addMessage("form:newEmail",
msg);
}
return;
}
And here is what happens:
- When field is empty (that is required="true" fails) both messages appear
fine.
- When value is not unique (we go into "catch (DuplicateEmailException ex)")
the field message is not shown. The <h:messages /> shows my message.
I know ajax4jsf has problems rendering components that are not initially
present. But then - I tried to use the suggested in the Developep's Guide
approach (with outputPanel) and it does not work for me.
Has anyone had similar experience? Any help will be appreciated.
Thanks,
Jana
