Question

我有一个带有动态列的primefaces数据表，并为显示搜索结果的每列进行过滤。每次使用update="@form"执行搜索后，数据表都会更新。不幸的是，在用户对列进行过滤之后，数据表不再更新。在执行搜索之后，数据表不显示新的搜索结果，直到用户更改视图并返回到数据表（搜索结果存储在会话中），这将从头开始构建数据表。

这是数据表xhtml：

    sortMode="multiple" rowKey="#{curSearchResult.hashCode()}" draggableColumns="true" resizableColumns="true" styleClass="hitlistDataTable"
    paginator="true" rows="#{curSearch.hitlistRowsPerPage}" rowIndexVar="rowIndex"
    paginatorTemplate="{FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}"
    rowsPerPageTemplate="#{curSearch.rowsPerPageTemplate}" paginatorPosition="bottom" tableStyleClass="searchResultTable"

Answer 1

您需要在搜索按钮时清除过滤。使用您的数据表的widgetVar="hitlistTableVar"然后

命令按钮上的

清除过滤器。

 oncomplete="hitlistTableVar.clearFilters();"

希望它能解决你的问题。

使用动态列和过滤的primefaces dataTable不再更新
