Firstly, sorry my english. I'm brazilian and I have a problem. I have a panelGroup that is duplicating the validation message when I use the component global messages. Look:
That is my page xhtml:
<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://xmlns.jcp.org/jsf/html"
xmlns:p="http://primefaces.org/ui">
<h:head>
<title>Facelet Title</title>
</h:head>
<h:body>
<h:form>
Hello from Facelets
<h:panelGroup binding="#{testeMB.panel}" >
<p:inputText id="field_id" value="#{testeMB.field}"
required="true" />
<p:commandButton id="button_id" value="Submeter"
action="#{testeMB.submit}" ajax="false" />
</h:panelGroup>
</h:form>
</h:body>
That is my ManagedBean:
@ManagedBean
@ViewScoped
public class TesteMB implements Serializable {
public static final long serialVersionID = 1L;
private HtmlPanelGroup panel;
private String field;
public TesteMB() {
}
public void submit() {
System.out.println("Form submited!!!");
}
// gets and sets
}
In the end, it prints the same message twice. Look:
Looking at the life cycle of the JSF in any cycle less RENDER_RESPONSE, there are 4 components. Has anyone here ever experienced this?
It was identified that this problem is going from version 2.1.22 onwards. What I do not know why. Thanks to everyone who tried.
