How to avoid displaying duplicate messages

[daclan]

I used EntityHome to persist my entity Order.java.

Each time I call persist() of EntityHome, there is a message Successful created added to FacesMessages. In my page order.xhtml, I can see this message with the jsf tag h:messages.

But when I persist Order.java, I have to persist also another entity  (ex. Command.java). So in this case, I see two times the same messages in my .xhtml (because I persisted two entities):

Successful created
Successful created

If I have to persist 5 other entities when I persist the entity Order.java, I will see 6 lines with the same information: Successful created.

I would like to know how can I do to display only one time the same message ?

Those messages are added to the FacesMessages object. Here's a link to the api for that. You could try using the clear method before you add another message.

http://www.redhat.com/docs/manuals/jboss/jboss-eap-4.3/doc/seam/api/org/jboss/seam/core/FacesMessages.html

Also, just for your information... Successful Created isn't proper English. You should say something like Successfully created  (object name).  Successfully created or Successful create would be technically ok, but aren't very user-friendly messages.

Just trying to help :)

Oh, and just to be more clear, you probably have a line of code wherever your persistence is happening that looks like:

@In
FacesMessages messages;

...

public void persist(){

 em.persist(myObject);
 messages.add("Successful created");

}

If you do messages.clear before you do messages.add, it would only appear once... but you can use that API listing to see how to manipulate it on your own.

Thanks Matt !

The EntityHome.java and Home.java added the messages Successfully created automatically each time I call persist() on my entity.

I found the way to change this message.
