Primefaces ajax 更新
我有 primefaces 数据表,
<p:panel id="resultpanel">
<p:dataTable id="tbl" var="job" value="#{report.jobModel}"
paginator="true" rows="#{report.jobModel.pageSize}"
paginatorPosition="bottom" lazy="true" scrollable="true"
resizableColumns="true" rendered="#{!empty report.jobModel}"
emptyMessage="#{messages['common.datatable.emptymessage']}">
<p:ajax event="filter" listener="#{report.jobModel.onFilter}"
update="@form" />
<p:column sortBy="#{job.detail4}" filterBy="#{job.detail4}">
<f:facet name="header">
<h:outputText value="#{messages['content.donejobs.ftdi.datatable.fixedfeecolumn.header']}" />
</f:facet>
<h:outputText value="#{job.detail4}">
<f:converter converterId="KurusLiraConverter"></f:converter>
</h:outputText>
</p:column>
<f:facet name="footer">
<h:outputFormat value="#{messages['content.donejobs.ftdi.datatable.footer']}">
<f:param value="#{report.jobModel.rowCount}" />
</h:outputFormat>
<p:panel layout="block" style="border: 0px; text-align: center;">
<p:commandLink ajax="false" title="Download Report">
<p:graphicImage value="/images/excel.png" />
<p:fileDownload value="#{report.excelFileOfReportTable}" />
</p:commandLink>
</p:panel>
</f:facet>
</p:dataTable>
</p:panel>
我想在过滤表时更新页脚部分。我尝试通过将页脚中的所有内容放入一个面板中来更新页脚,为其提供一个 ID,通过 firebug 检查此 ID,并将其作为 primefaces ajax 组件的 update 属性的值。我也对 html 输出格式和参数组件执行了这种方法。但没有成功,最后我尝试更新表单,这次整个表格已经像文本文件一样呈现。有没有办法在过滤后更新表大小?顺便说一下,我使用的是 primefaces 3.0.RC1-SNAPSHOT,并在 firefox 7.0.1 中进行测试。非常感谢您的关注和评论。

I want to update the footer part when I filter the table. I have tried to update the footer by putting all the things in the footer in a single panel, giving it an ID, inspecting this ID via firebug, and giving it as a value to the update attribute of the primefaces ajax component. I have also performed this approach, to html outputformat and param components. But no success, lastly I have tried to update the form, this time the whole table has been rendered like a text file. Is there a way to update the table size, after filtering? By the way, I am using primefaces 3.0.RC1-SNAPSHOT, and testing in firefox 7.0.1. Thank you very much for your interest and comment.

此处有一个未解决的问题,他们提供了补丁为数据表代码。我的解决方法(又名巨大的黑客)不需要接触 primefaces 代码库,这是我更喜欢的。我针对下面的事件测试了它,但我不明白为什么它不适用于 rowEdit 事件。
是的,我使用 ap:remoteCommand (由 p:ajax 中的 oncomplete 客户端挂钩调用)来更新页脚行内的组件。与数据本身相比,这会导致页脚更新出现微小的延迟,但我可以忍受。
There is an open issue for that here and they provide a patch for the dataTable code. My workaround (aka huge hack) doesn't require touching the primefaces codebase, which I prefer. I tested it for the events below, but I can't see why it wouldn't work for the rowEdit event.
Yes, I use a p:remoteCommand (invoked by the oncomplete client-side hook in p:ajax) to update the components inside the footer row. This causes a tiny delay on the footer update in comparison to the data itself, but I can live with that.
3.0.RC1-SNAPSHOT 不是正式版本,据我所知,它可能意味着 M4 之后或 M3 和 M4 之间的任意数量的夜间构建。您应该升级(或降级?)到稳定版本,例如 M3 或 M4,看看是否遇到相同的问题。
您也可以尝试 update="@this",但我不确定这会产生什么效果,而 @form 不应该起作用。
3.0.RC1-SNAPSHOT is not an official release, and from what I can tell it could mean any number of nightly builds after M4 or between M3 and M4. You should upgrade (or downgrade?) to a stable release such as M3 or M4 and see if you get the same problems.
Also you could try update="@this", but I'm unsure what effect that would have that shouldn't already work with @form.
