4. Action is not triggered after a submit
jsf in its methods should have the following signature:
for action = "#" should return a string and has no parameters eg
public String excluir(){
return "";
}
or to be void ActionListener and ActionEvent as a parameter eg
public void excluir(ActionEvent evt){
..
}

Well I'm using Facelets + JSF
So, why the method "pesquisar()" works fine?
And also, If I move the buttons "Gravar" to the search block, they start to work!
-
7. Action is not triggered after a submit
Isso não sei responder mas a especificação JSF diz que as actions tem que ter tipo de retorno String e as actionListener's tem que ser void com parametro ActionEvent.
Experimente mudar a assinatura dos seus metodos para ver se funciona, lembre- se tambem de sempre envolver seus componentes dentro de um form, pois erros deste tipo quase sempre sao causados pela falta de um form.

8. Action is not triggered after a submit
Well... after some tests I continue with problemas.
Anybody else can help me?

9. Action is not triggered after a submit
I cannot understand your code, it's probably not english language, unable to figure out your saving mechanisim in beans.
-
10. Action is not triggered after a submit
hi,
if it is one of your commandbuttons with rendered attribute has problem, maybe because your holdingbean is request scope.

Aman, thanks for your reply. You're rigth. My code use portuguese language!
Think about the transformation below to understand the code.
pesquisar, listar = search
inserir, incluir = insert
alterar, editar = update
excluir, apagar = delete
If you have some another consideration, please, let me know.
Thanks,

Hi liumin hu,
i have change the bean's scope to application, and works.
Do you know why the request scope cause this behavior?
Thanks.
-
13. Action is not triggered after a submit
Request scope bean is initiated every reques so the rendered attribute is false at begining.
and the JSF ignore the component with "rendered = false" when it restore the view(phase 1). At phase render response(phase 6), the rendered became true, so you can see it. but the component is not in the view, the action is ignored too.
-
14. Action is not triggered after a submit
Hi again Iimin hu!
Well... I have tested some resources after the update to application scope. But unfortunally I can't use application scope to this case in my application.
So what can I do about it? Session scope is not a good ideia... So I just can use request scope.
