  • And in the browser log, something appears?

  • where specifically you are referring to?

  • For example, in Google Chrome, you can view the log by the Ctrl+Shift+j shortcut, and you can also run Javascript instructions.

  • Got it, I’ll check

  • see if this helps

You are trying to manually program the call to confirm. That’s not the idea. The idea is that the confirm override the standard Javascript confirmation, then you program the button normally to do what you have to do, and configure it to invoke a confirmation when the button is clicked.

So you don’t need to schedule the call from confirm. Instead, you set the button so that the confirmation window is automatically invoked.

Your code should look something like this:

                    <p:commandButton icon="ui-icon-trash" title="Excluir" 
                        actionListener="#{bean.excluir()}">
                        <p:confirm header="Exclusão de produto" 
                            message="Tem certeza que deseja excluir o produto?" 
                            icon="ui-icon-alert" />
                    </p:commandButton>
                </p:column>
            </p:dataTable>

            <p:confirmDialog global="true">
                <p:commandButton value="Não" type="button" 
                    styleClass="ui-confirmdialog-yes" icon="ui-icon-check"/>
                <p:commandButton value="Sim" type="button" 
                    styleClass="ui-confirmdialog-no" icon="ui-icon-close"/>
            </p:confirmDialog>

See the differences with respect to your original code:

  • I gave a function to the delete button (in this case, the dummy method call bean.delete, which will be done by Primefaces using Ajax).

  • I specified a tag p:confirm to the button. It is responsible for triggering the confirm.

  • header and message are specified in tag p:confirm, because the dialog is generic.

  • I added the property global at the confirm. This component, in turn, has no explicitly programmed action. It is the classes ui-confirmdialog-yes and ui-confirmdialog-no on the buttons identifying which button the user clicked. So if the user clicks "Yes", the method associated with the button "Rule out" (in the case, bean.delete) will be invoked.
