Question

如果我只进入页面并且我不使用过滤器，我点击按钮并且工作得非常好，我可以更新该字段。但如果我使用一些过滤器，就不再工作了。有帮助吗？对不起我的英语顺便说一句。这就像我过滤数据时丢失，并为按钮目标发送空值。

<h:form>  
                <p:commandButton style="margin-bottom: 10px;" value="Criar Produto de catalogo" action="admin_create_cProduct?faces-redirect=true" />

我忘了将filteredValue放入<p:dataTabel> 现在解决方案：

<p:dataTable
                    var="cProduct"
                    widgetVar="cProductTable"
                    summary="Lista de produtos de catalogo"
                    value="#{administratorManager.catalogProduct}"
                    emptyMessage="No catalog product found" rows="25" paginator="true"
                      paginatorTemplate=" {FirstPageLink} {PreviousPageLink} {CurrentPageReport}  {NextPageLink}  {LastPageLink} {RowsPerPageDropdown}"
                      rowsPerPageTemplate="5,25,50" filteredValue="#{administratorManager.filteredcProduct}">

感谢各位帮忙。
