p：commandButton action和f：setpropertyactionlistener未在p：columngroup中调用 [英] p:commandButton action and f:setpropertyactionlistener not invoked in p:columngroup

问题描述

我需要将子组件放置在字母子页脚（p：columngroup type =footer）中，但标准子表单渲染器不提供此类机会。所以我已经覆盖了org.primefaces.component.SubTableRenderer来添加子渲染：

I need to put child components in primefaces subtable footer (p:columngroup type="footer"), but standard subtable renderer doesn't provide such opportunity. So I have overrided org.primefaces.component.SubTableRenderer to add children rendering:

public class CustomSubTableRenderer extends SubTableRenderer{
@Override
protected void encodeColumnFooter(FacesContext context, SubTable table, Column column) throws IOException {
    ResponseWriter writer = context.getResponseWriter();

    String style = column.getStyle();
    String styleClass = column.getStyleClass();
    styleClass = styleClass == null ? DataTable.COLUMN_FOOTER_CLASS : DataTable.COLUMN_FOOTER_CLASS + " " + styleClass;

    writer.startElement("td", null);
    writer.writeAttribute("class", styleClass, null);
    if(column.getRowspan() != 1) writer.writeAttribute("rowspan", column.getRowspan(), null);
    if(column.getColspan() != 1) writer.writeAttribute("colspan", column.getColspan(), null);
    if(style != null) writer.writeAttribute("style", style, null);

    //encode children
    for(UIComponent footerColumnChild : column.getChildren()) {
        if(footerColumnChild.isRendered()) {
            footerColumnChild.encodeAll(context);
        }
    }

   UIComponent facet = column.getFacet("footer");
    String text = column.getFooterText();
    if(facet != null) {
        facet.encodeAll(context);
    } else if(text != null) {
        writer.write(text);
    }

    writer.endElement("td");
}

}

当我把一些子组件放在p：列组中，如：

When I put some child components in p:column group like:

<p:dataTable>
            <p:subTable>
                <p:column>..</p:column>
                <p:columnGroup type="footer"> <p:row> <p:column colspan="3">
                    <p:commandButton id="button" 
                                     action="#{myBean.someAction}"
                                     oncomplete="jQuery('#select').modal('show');return false;"
                                     value="#{val.add}" alt="#{val.add}"
                                     title="#{val.add}"> </p:commandButton>
                    <f:setPropertyActionListener value="#{otherBean.id}"
                                                 target="#{anotherBean.selectedBackId}" /></p:column> </p:row>
                </p:columnGroup> </p:subTable>
        </p:dataTable>

按钮被渲染，onClick事件调用正常，但是按钮的动作也没有f：setPropertyActionListener不会调用。如何使它们工作？

Button is rendered and onClick event invokes fine, but neither button's action nor f:setPropertyActionListener don't invokes. How to make them work?

如果我更改p：columnGroup type =footer结构到p：列标签比按钮动作和f：setPropertyActionListener都工作正常p>

if I change p:columnGroup type="footer" construction to p:column tag than button action and f:setPropertyActionListener both work fine

推荐答案

PrimeFaces有一个错误，其中commandButton或commandLink不会触发动作侦听器，如果它位于头部（源 - 见第二个缺陷）。我有一个希望，你在页脚中遇到了同样的问题。

PrimeFaces has a bug wherein a commandButton or commandLink doesn't fire the action listener if it is located in the header (source - see second defect). I have a hunch you've encountered the same problem in the footer.

这是在最近的版本中修复的，但还没有公开。如果您想使用PrimeFaces按钮（而不是标准的HTML按钮），则必须购买PrimeFaces Elite订阅或从头开始编译源代码。

This was fixed in a recent release, but it's not yet available to the public. If you want to use a PrimeFaces button (rather than a standard HTML button), you will have to buy a PrimeFaces Elite subscription or compile the source from scratch.
