在JSF2中双击Richfaces extendedDataTable时，获取所选项目 [英] Get selected item when double clicking on a Richfaces extendedDataTable in JSF2

问题描述

在我的JSF 2应用程序中，我有一个Richfaces extendedDataTable。当我双击一行时，我想离开此页面，我将在其他页面上显示所选表项的详细信息。我在表页中尝试了以下内容：

 < rich：extendedDataTable 
 value =＃{bean.loadedAnfragen }var =anfrage
 selection =＃{bean.selectedAnfrage}id =anfragenTable
 selectionMode =single
 onrowdblclick =showAnfrage（）;> 
 
 ...这里是我的列... 
 
< / rich：extendedDataTable> 
 
< a4j：jsFunction name =showAnfrageaction =＃{bean.showAnfrage}/> 
  

bean中的方法被调用，但选择（双击的行）为null。这是适当方法的代码：

  public void showAnfrage（）{
 
 UIExtendedDataTable table = （UIExtendedDataTable）FacesContext.getCurrentInstance（）。getViewRoot（）。findComponent（mainForm：anfragenTable）; 
 
 if（table！= null）{
 for（Object selection：table.getSelection（））{
 System.out.println（Thats the selected object：+选择）; 
} 
} 
} 
  

我还尝试了一些ajax的东西。我想通过 f：setPropertyActionListener 在 a4j：ajax 标签中传递选项，但这是不可能的，因为datatable本身是没有动作源，所以setPropertyActionListener标签不能被调用。
Doeas任何人都有一个解决方案来获取选择的项目，在双引号的extendedDataTable行？

解决方案

我已经实现了onrowclick：

 < a4j：jsFunction name =selectRowaction =＃{chAction.selectClient}> 
< a4j：param name =selectedClientIdassignTo =＃{chAction.selectedClientId}/> 
< / a4j：jsFunction> 
 
< rich：dataTable id =chTable
 rows =＃{referenceData.recordsPerPage}style =width：100％
 value =＃{chAction .clients}var =ressortMode =single
 rowClasses =oddrow，evenrow
 onrowclick =selectRow（'＃{res.clientId}'）
 rowKeyVar = currRow> 
  

您可以将事件更改为双点击。

In my JSF 2 application I have a Richfaces extendedDataTable. When I doubleclick on a row I want to leave this page and I will display the details of the selected table entry on this other page. I tryied the following in the table page:

<rich:extendedDataTable 
    value="#{bean.loadedAnfragen}" var="anfrage"
    selection="#{bean.selectedAnfrage}" id="anfragenTable"
    selectionMode="single" 
    onrowdblclick="showAnfrage();">

    ... here are my columns ...

</rich:extendedDataTable>

<a4j:jsFunction name="showAnfrage"  action="#{bean.showAnfrage}" />

The method in the bean gets called but the selection (the row where I double clicked) is null. This is the code for the appropriate method:

public void showAnfrage() {

    UIExtendedDataTable table = ( UIExtendedDataTable )FacesContext.getCurrentInstance().getViewRoot().findComponent( "mainForm:anfragenTable" );

    if( table != null ) {
        for( Object selection : table.getSelection() ) {
            System.out.println( "Thats the selected object: " + selection );
        }
    }
}

I also tried some ajax stuff. I wanted to pass the selection with f:setPropertyActionListener inside an a4j:ajax tag but this is impossible because the datatable itself is no action source so the setPropertyActionListener tag cannot be called. Doeas anyone has a solution for getting the selected item after doubliclicking the extendedDataTable row?

解决方案

I have implemented it with onrowclick:

    <a4j:jsFunction name="selectRow" action="#{chAction.selectClient}">
        <a4j:param name="selectedClientId" assignTo="#{chAction.selectedClientId}" />
    </a4j:jsFunction>

    <rich:dataTable id="chTable"
        rows="#{referenceData.recordsPerPage}" style="width: 100%"
        value="#{chAction.clients}" var="res" sortMode="single"
        rowClasses="oddrow, evenrow"
        onrowclick="selectRow('#{res.clientId}')"
        rowKeyVar="currRow" >

You can change event to double click.
