Ever wonder what is the difference between a commandToolBarButton and the commandButton
here it goes
CommandToolBarButton – partialSubmit – Default Value: true
whether the action should be done through a partial page submit or not. The default is true for commandToolBarButton, so be sure to specify partialTriggers if content needs to be updated.
CommandButton – partialSubmit – Default Value: false
whether the action should be done through a partial page submit or not. Default is false: no partial page submit; the full page will be refreshed. When set to true, the full page will not be refreshed. To re-render specific components on your page in response to the partial page submit, you have to tell ADF Faces. The easiest way to do this is with the partialTriggers attribute.
