Primefaces 严重错误：呈现视图时出错，无法将字符串转换为整数自定义筛选器素数
我想使用自定义筛选器筛选列。列的类型为字符串 my page index.xhtml类似于：Primefaces 严重错误：呈现视图时出错，无法将字符串转换为整数自定义筛选器素数,primefaces,filtering,jsf-2.2,Primefaces,Filtering,Jsf 2.2,我想使用自定义筛选器筛选列。列的类型为字符串 my page index.xhtml类似于： <p:dataTable id="tab" var="v" value="#{registerVehicule.listVehicules}" filteredValue="#{registerVehicule.filteredV}" selection="#{registerVehicule.selectedV}" rowKey="#{v.idVehicule}" scr

有人能帮我吗？？我使用的是Primefaces 5，我认为您只需要正确的方法签名。从： filterFunction应该是一个具有三个参数的方法；列值， 筛选值和区域设置。返回值为布尔值，true接受 值和false将拒绝它
public boolean filterByPrice(Object value, Object filter, Locale locale) {
//return true or false
}
