如何在javax.el.MethodExpression中传递多个参数

Question

我正在尝试为org.primefaces.component.poll.Poll-创建方法表达式

MethodExpression methodExpression = exprFactory
            .createMethodExpression(elContext,
                    "#{requestManagementBackingBean.addDiffDatatable("
                            + parentGrid +","+action+ ")}", void.class,
                            classList);

pollForDatatable.setListener(methodExpression);

在这种情况下，呈现页面时出现错误-
