org.nuxeo.ecm.platform.webapp.base.properties nuxeo.jsf.ajax.disableErrorFeedback: disables JavaScript hook displaying an error message in the JSF UI when an empty response is received from server. Disabling this hook is not recommended, but this can be useful on a slow server when users do not want to see this message on some concurrent requests (when server is down, no message will be displayed on Ajax actions). false
