Examples with ValueChangeListener jakarta.faces.event.ValueChangeListener used on opensource projects

Example 1 with ValueChangeListener

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

the class ValueChangeListenerHandler method applyAttachedObject.

@Override
public void applyAttachedObject(FacesContext context, UIComponent parent) {
    // Retrieve the current FaceletContext from FacesContext object
    FaceletContext faceletContext = (FaceletContext) context.getAttributes().get(FaceletContext.FACELET_CONTEXT_KEY);
    EditableValueHolder evh = (EditableValueHolder) parent;
    ValueExpression b = null;
    if (this.binding != null) {
        b = this.binding.getValueExpression(faceletContext, ValueChangeListener.class);
    }
    ValueChangeListener listener = new LazyValueChangeListener(this.listenerType, b);
    evh.addValueChangeListener(listener);
}

Example 2 with ValueChangeListener

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

the class FaceletViewDeclarationLanguage method applyValueChangeListenerMethodExpressionTarget.

private void applyValueChangeListenerMethodExpressionTarget(FacesContext context, FaceletCompositionContext mctx, ELContext elContext, UIComponent topLevelComponent, UIComponent innerComponent, String attributeName, String targetAttributeName, String attributeExpressionString, ValueExpression attributeNameValueExpression, boolean ccAttrMeRedirection) {
    ValueChangeListener o = (ValueChangeListener) mctx.removeMethodExpressionTargeted(innerComponent, targetAttributeName);
    if (o != null) {
        ((EditableValueHolder) innerComponent).removeValueChangeListener(o);
    }
    // target is EditableValueHolder
    ValueChangeListener valueChangeListener = null;
    // If it is a redirection, a wrapper is used to locate the right instance and call it properly.
    if (ccAttrMeRedirection) {
        valueChangeListener = new RedirectMethodExpressionValueExpressionValueChangeListener(attributeNameValueExpression);
    } else {
        MethodExpression methodExpression = reWrapMethodExpression(context.getApplication().getExpressionFactory().createMethodExpression(elContext, attributeExpressionString, Void.TYPE, VALUE_CHANGE_LISTENER_SIGNATURE), attributeNameValueExpression);
        MethodExpression methodExpression2 = reWrapMethodExpression(context.getApplication().getExpressionFactory().createMethodExpression(elContext, attributeExpressionString, Void.TYPE, EMPTY_CLASS_ARRAY), attributeNameValueExpression);
        if (mctx.isUsingPSSOnThisView()) {
            valueChangeListener = new PartialMethodExpressionValueChangeListener(methodExpression, methodExpression2);
        } else {
            valueChangeListener = new MethodExpressionValueChangeListener(methodExpression, methodExpression2);
        }
    }
    ((EditableValueHolder) innerComponent).addValueChangeListener(valueChangeListener);
    mctx.addMethodExpressionTargeted(innerComponent, targetAttributeName, valueChangeListener);
}

    EditableValueHolder evh = (EditableValueHolder) parent;
    ValueExpression b = null;
    if (binding != null) {
        b = binding.getValueExpression(ctx, ValueChangeListener.class);
    }
