Example 1 with UiState

use of org.opennms.features.vaadin.jmxconfiggenerator.ui.UiState in project opennms by OpenNMS.

the class JmxConfigGeneratorUI method initNavigator.

    navigator.addView(UiState.ResultConfigGeneration.name(), new Navigator.EmptyView());
    // We need to hook into the "view change" process to prevent changing to the "working views"
    // Instead we trigger a long running task and show a "please wait" window.
