过滤数据后，原型会丢失对话框中的数据 [英] Primefaces loses data in dialog after filter the datatable

问题描述

我有一个问题，关于字典datatable。我建立了一个仪表板，人们可以在其中查找一些东西。所以在datatable中显示了数据库中的一些值。每一行都有一个按钮来获得更多的细节。所以如果你点击这个按钮，它会打开一个对话框，并提供一些更多的细节。数据表中的某些值显示在对话框中，还有一些显示在对话框中。所以这是正常工作。现在我发现过滤器在对话框中删除了我的值。当我使用过滤器功能时，他过滤我的值，更新和呈现新的datatable，当我点击按钮现在，对话框中的值已经消失。为什么？

我已经google了这个问题，但没有找到一个解决方案。可能有人可以帮助？

解决方案

如果您过滤 dataTable 定义 filteredValue 属性 dataTable ，表示您过滤的数据。它应该与 dataTable 的值属性相同。

Hi guys i have a problem, concerning the primefaces datatable. i built a dashboard, where people can look up some things. so in the datatable are shown some values from the database. every row got a button for more special details. so if you click on this button it opens a dialog frame with some more details. some of the values of the datatable are shown in the dialog and some more too. so this is working fine. now i figured out that the filter deletes my values in the dialog frame. when i use the filter function he filters my values, update and render the new datatable and when i click the button now, the values in the dialog frame are gone. why?

<h:form id="form1">
    <p:dataTable value="#{auftragBean.auftragsDaten}" var="auftrag"
        rowKey="#{auftragBean.auftragsDaten}" selectionMode="single">

        <f:facet name="header">
            ...
        </f:facet>

        <p:column style="width:200px;text-align:center"
            filterBy="#{auftrag.schadennummer}" headerText="Schadennummer"
            filterMatchMode="contains">
                #{auftrag.schadennummer}
            </p:column>

        <p:column headerText="Auftragsbericht" style="text-align:center">
            <p:commandButton styleClass="viewbutton" icon="ui-icon-search"
                style="border-left:1px solid #666; height:20px;font-size:10px;"
                oncomplete="PF('dlg').show();" value="Open"
                actionListener="#{auftragBean.initSelectedData(auftrag)}"
                update="@widgetVar(dlg)" process="@this"></p:commandButton>
        </p:column>
    </p:dataTable>




<p:dialog appendToBody="true" appendTo="@(body)" modal="true"
        id="dialog" resizable="false"
        header="Auftragsbericht &nbsp;&nbsp;-&nbsp;&nbsp; #{auftragBean.auftragsData.jobId}"
        widgetVar="dlg" showEffect="drop" hideEffect="drop">
        <div style="max-height: 1000px; padding-right: 20px">

            <p
                style="margin-top: 10px; color: black; font-size: 16px; padding-bottom: 0px; text-align: center;">
                <b>Bearbeitungsverlauf</b>
            </p>
            <div class="berichtTabelle">

                        value="#{auftragBean.berichtsDaten}" var="bericht"
                        rowKey="#{bericht.tickerId}" selectionMode="single">

                        <f:facet name="header">
                            <p:outputPanel style="height:20px">
                                <h:outputText value="Bearbeitungsverlauf"
                                    style="float:left;font-size:14px;" />
                            </p:outputPanel>
                        </f:facet>

                        <p:column style="text-align:center" headerText="Status">
                            #{bericht.status}
                        </p:column>

                    </p:dataTable>
                </h:form>
            </div>
        </div>
    </p:dialog>   </h:form>

I have googled for this problem but havent found a solution. Maybe someone can help?

If you filter dataTable, your should define filteredValue attribute of dataTable, which represents your filtered data. It should be the same type as value attribute of this dataTable.
