Hibernate validator and more error messages

[martin.krajci]

Hi conference,

I'm using hibernate validators in my Seam application:

xhtml:

<s:decorate id="numberOfNightsDecoration" template="validate.xhtml">
 <h:outputLabel value="#{msg.number_of_nights}" for="#{msg.number_of_nights}"/>
 <h:inputText value="#{reservation.numberOfNights}" id="#{msg.number_of_nights}" required="true">
 <a:support event="onblur" ajaxSingle="true" reRender="numberOfNightsDecoration">
 <s:conversationId/>
 </a:support>
 </h:inputText>
 </s:decorate>

java:

@Min(value=1, message="#{messages['validator.min']}")
 @Max(value=100, message="#{messages['validator.max']}")
 @Column(name = "number_of_nights", unique = false, nullable = false, insertable = true, updatable = true)
 public int getNumberOfNights() {
 return numberOfNights;
 }

and when I submit the UI form I with value 0 for numberOfNights I get more the same error messages in h:messages component.

<f:subview rendered="#{! empty facesContext.maximumSeverity}">
 <div class="errors">
 <div><h:messages/></div>
 </div>
 </f:subview>

something like this:

# Value is too small
# Value is too small
# Value is too small
.

Do you have any idea why the error message is dispalyed in UI more times?

Thanx for any help.

You probably want to use globalOnly on h:messages

Thanx for your reply, but I don't want to because some pages have more than 50 input fields and then for each I would have to create <h:message for"xy"/>

Do you have any other ideas?

But you are using s:decorate... or you want all your messages displayed together...

Anyway, the problem (I think) is that your ajax stuff is causing multiple messages to be enqueued, but renderered all at once. Try putting the messages component into an ajax-rerendered region. Or don't use a:support if you aren't using ajax validation.

Yes I want to display messages together.

I also thought that ajax might be a problem but right now I'm in the phase of project where I can not simply remove it.

What do you mean by: "Try putting the messages component into an ajax-rerendered region."? Put it into the <s:decorate>here? -> also not possible.

Do you have any more ideas?

Use <a:outputPanel />
