数据表中的jsf2 f:ajax渲染问题 [英] jsf2 f:ajax render issue in datatable

问题描述

我有一个数据表，每行都有一个delete link命令，如下所示:

I have a datatable and for each line have a delete linkcommand, as following:

<h:dataTable value='#{glbProjectDtoList}' var='projectDto'
    binding='#{projectController.projectDataTable}' styleClass='display'
    id='tblProject' rowClasses='gradeA, gradeA'
    columnClasses='projectTableName, projectTableProgress, projectTableAction'>
    ......
    <h:commandLink
        action="#{projectController.delete(projectDto.projectId)}">
        <img class="btnDeleteProject mr5"
            src="#{request.contextPath}/resources/images/icons/dark/trash.png" />
        <f:ajax execute="@form"
            onevent="function(data) {deleteProjectEventHandler(data);}"
            render=":tblProject" />
    </h:commandLink>
    ......
</h:dataTable>

delete函数可以正常工作，但是整个数据表都不会重新呈现，是因为操作嵌套在数据表中还是由于其他原因?

The delete function works fine, but the whole datatable is not reRendered, is it because the action nested in data table or by some other reason?

更新:

它不起作用，删除(:)后，引发以下异常:

It's not working, after remove (:), throw following exception:

    javax.faces.FacesException: <f:ajax> contains an unknown id 'tblProject' - cannot locate it in the context of the component j_idt68

表示不包含(:)，该元素必须位于同一h:form标记中.

means without (:), the element must be in same h:form tag.

谢谢.

推荐答案

我采用了另一种方法，在表外使用隐藏表格.可以.

I have go another approach, use hiding form outside of the table. It works.
