Example 1 with ActionEvent

use of jakarta.faces.event.ActionEvent in project myfaces by apache.

the class UIViewAction method broadcast.

@Override
public void broadcast(FacesEvent event) throws AbortProcessingException {
    super.broadcast(event);
    FacesContext context = getFacesContext();
    if (context.getResponseComplete()) {
        return;

                context.getAttributes().put(BROADCAST_PROCESSING_KEY, oldBroadcastProcessing == null ? Boolean.FALSE : oldBroadcastProcessing);
            }
            if (context.getResponseComplete()) {

                    context.renderResponse();
                }
            // "... Otherwise, execute the lifecycle on the new UIViewRoot ..."
            // Note these words are implemented in the NavigationHandler, but
            // the original proposal from seam s:viewAction did a trick here
            // to restart the JSF lifecycle.
            }
        }
    }
}

Example 2 with ActionEvent

use of jakarta.faces.event.ActionEvent in project myfaces by apache.

the class UIViewAction method decode.

@Override
public void decode(FacesContext context) {
    super.decode(context);
    if (context.isPostback() && !isOnPostback()) {
        return;
    }
    if (!isRendered()) {
        return;
    }
    ActionEvent evt = new ViewActionEvent(this);
    String phase = getPhase();
    PhaseId phaseId = phase != null ? PhaseId.phaseIdValueOf(phase) : isImmediate() ? PhaseId.APPLY_REQUEST_VALUES : PhaseId.INVOKE_APPLICATION;
    evt.setPhaseId(phaseId);
    this.queueEvent(evt);
    // "... Keep track of the number of events that are queued in this way
    // on this run through the lifecycle. ...". The are two options:
    // 1. Use an attribute over FacesContext attribute map
    // 2. Use an attribute over the component
    // If the view is recreated again with the same viewId, the component
    // state get lost, so the option 1 is preferred.
    Integer count = (Integer) context.getAttributes().get(EVENT_COUNT_KEY);
    count = (count == null) ? 1 : count + 1;
    context.getAttributes().put(EVENT_COUNT_KEY, count);
}

Example 3 with ActionEvent

use of jakarta.faces.event.ActionEvent in project myfaces by apache.

        ActionListener defaultActionListener = context.getApplication().getActionListener();
        if (defaultActionListener != null) {
            defaultActionListener.processAction((ActionEvent) event);
        }
    }
}

Example 4 with ActionEvent

use of jakarta.faces.event.ActionEvent in project myfaces by apache.

the class HtmlLinkRendererBase method decode.

@Override
public void decode(FacesContext facesContext, UIComponent component) {
    // check for NP
    super.decode(facesContext, component);
    if (component instanceof UICommand) {
        String clientId = component.getClientId(facesContext);
        UIForm form = ComponentUtils.findClosest(UIForm.class, component);
        boolean disabled = HtmlRendererUtils.isDisabled(component);
        // MYFACES-3960 Decode, decode client behavior and queue action event at the end
        boolean activateActionEvent = false;
        if (form != null && !disabled) {
            String reqValue = (String) facesContext.getExternalContext().getRequestParameterMap().get(HtmlRendererUtils.getHiddenCommandLinkFieldName(form, facesContext));
            activateActionEvent = reqValue != null && reqValue.equals(clientId) || HtmlRendererUtils.isPartialOrBehaviorSubmit(facesContext, clientId);
        }
        if (component instanceof ClientBehaviorHolder && !disabled) {
            ClientBehaviorRendererUtils.decodeClientBehaviors(facesContext, component);

        if (activateActionEvent) {
            component.queueEvent(new ActionEvent(component));
        }
    } else if (component instanceof UIOutput) {
        // do nothing
        if (component instanceof ClientBehaviorHolder && !HtmlRendererUtils.isDisabled(component)) {
            ClientBehaviorRendererUtils.decodeClientBehaviors(facesContext, component);
        }
    } else {
        throw new IllegalArgumentException("Unsupported component class " + component.getClass().getName());
    }
}

Example 5 with ActionEvent

use of jakarta.faces.event.ActionEvent in project myfaces by apache.

the class HtmlButtonRendererBase method decode.

@Override
public void decode(FacesContext facesContext, UIComponent uiComponent) {
    RendererUtils.checkParamValidity(facesContext, uiComponent, UICommand.class);
    // super.decode must not be called, because value is handled here
    boolean disabled = isDisabled(facesContext, uiComponent);
    // MYFACES-3960 Decode, decode client behavior and queue action event at the end
    boolean activateActionEvent = !isReset(uiComponent) && isSubmitted(facesContext, uiComponent) && !disabled;
    if (uiComponent instanceof ClientBehaviorHolder && !disabled) {
        ClientBehaviorRendererUtils.decodeClientBehaviors(facesContext, uiComponent);
    }
    if (activateActionEvent) {
        uiComponent.queueEvent(new ActionEvent(uiComponent));
    }
