Jsf 嵌套复合组件：父级尝试获取子级属性

一方面，我在自定义复合组件（ListApaginadComposite）中有一个primefaces数据表，用户可以在其中的列中添加他们想要的任何内容

另一方面，我有另一个自定义复合组件（ListaValoresComposite），我将其插入到第一个组件的一个列中

或多或少，这没关系，但当父组合刷新自身时，我会得到

PropertyNotFoundException

，因为它试图在自身中获取子属性（“child”）。我在试图解决这个问题时快发疯了，有人知道如何让myfaces正确地解析

{cc}

，父对象还是子对象，而不是总是解析为父对象吗？ValueExpression的位置指向正确的xhtml（listaValores.xhtml），但#{cc}始终解析为ListaPaginadaComposite

我正在使用Primefaces 6.1和Myfaces 2.2.12

什么意思，

javax.el.PropertyNotFoundException:Propiedad'child'无hallada en el tipo atlas.componentes.composite.ListaPaginadaComposite

？

“javax.el.PropertyNotFoundException:Poperty'child'未在atlas.componentes.composite.ListaPaginadaComposite类型上找到”

这意味着它正在查找属于

listaValores

（声明为

{cc.child.column}

）但在“listaPaginada”中的属性

子属性

，即父组合而不是正确的组合<代码>我不知道如何设置答案中的代码格式。。
