在 Oracle ADF Faces 中获取表的渲染属性时出错

发布于 2024-12-12 08:11:26 字数 607 浏览 0 评论 0原文

我正在尝试在预渲染阶段期间渲染/不渲染表格。我正在使用 jDev 10.3.1.4

我设置了一个带有“rendered”属性设置的表，如下所示：

<af:table binding="#{backingBean.table1}" banding="row"
                rendered="#{backingBean.table1.rendered}">

在支持 bean 中我做了

protected void onPagePreRender(PagePhaseEvent event) {
     getTable1().setRendered(false);
     AdfFacesContext.getCurrentInstance().addPartialTarget(getTable1());
}

并且我不断收到错误Error getting property 'rendered' from bean of type of oracle。 adf.view.faces.component.core.data.CoreTable

我该如何解决这个问题？

I'm trying to render/not render a table during the preRender Fase. I'm using jDev 10.3.1.4

I set up a table with the "rendered" attribute set like this:

<af:table binding="#{backingBean.table1}" banding="row"
                rendered="#{backingBean.table1.rendered}">

In the backing bean i did

protected void onPagePreRender(PagePhaseEvent event) {
     getTable1().setRendered(false);
     AdfFacesContext.getCurrentInstance().addPartialTarget(getTable1());
}

And i keep getting the error Error getting property 'rendered' from bean of type oracle.adf.view.faces.component.core.data.CoreTable

How can i solve this?

删除 rendered 属性。它基本上是在无限循环中引用自身。如果您已经通过绑定引用的组件以编程方式操作它，则不需要它。

如果您确实打算使用 rendered 属性，正确的用法是

<af:table binding="#{backingBean.table1}" banding="row"
    rendered="#{backingBean.rendered}">

：

private boolean rendered = true;

protected void onPagePreRender(PagePhaseEvent event) {
    rendered = false;
    AdfFacesContext.getCurrentInstance().addPartialTarget(getTable1());
}

public boolean isRendered() {
    return rendered;
}

Remove the rendered attribute. It's basically referencing itself in an infinite loop. You don't need it if you already programmatically manipulate it by the component referenced by binding.

If you really intend to use the rendered attribute, the proper usage would be:

<af:table binding="#{backingBean.table1}" banding="row"
    rendered="#{backingBean.rendered}">

with

private boolean rendered = true;

protected void onPagePreRender(PagePhaseEvent event) {
    rendered = false;
    AdfFacesContext.getCurrentInstance().addPartialTarget(getTable1());
}

public boolean isRendered() {
    return rendered;
}
