如何嵌入输入组件,例如一个 selectOneMenu 到一个 PickList?
How do I embed an input component like e.g. a selectOneMenu into a PickList?
当我将 value 属性放入 selectOneMenu value="#{customer.customerType}"
时出现以下错误:
javax.el.PropertyNotFoundException: Target Unreachable, identifier 'customer' resolved to null
选择列表:
<p:pickList id="customersPL" itemLabel="#{customer.id}"
itemValue="#{customer}" responsive="true"
value="#{bean.customersList}" var="customer">
<o:converter converterId="omnifaces.ListConverter"
list="#{bean.customersListSource}" />
<p:ajax event="transfer" listener="#{bean.onTransfer}" />
<p:column>
<h:outputText value="#{customer.name}" />
</p:column>
<p:column>
<p:selectOneMenu converter="omnifaces.SelectItemsConverter"
id="customerType" value="#{customer.customerType}">
<f:selectItems itemLabel="#{customerType.name}"
itemValue="#{customerType}"
value="#{bean.customerTypesList}"
var="customerType" />
</p:selectOneMenu>
</p:column>
</p:pickList>
豆子:
private CustomerType[] customerTypesList = CustomerType.values();
CustomerType 枚举:
public static enum CustomerType {
WHOLESALE("W", "Wholesale"), RETAIL("R", "Retail");
private String id;
private String name;
TipoCliente(String id, String name) {
this.id = id;
this.name = name;
}
public String getId() {
return id;
}
public String getName() {
return name;
}
}
选择列表通常不包含输入 'controls'。所以 p:pickList
从未被设计为包含像 h\p:selectonemenu
甚至普通的 h\p:inputTexts
这样的输入。所以它不像你期望的那样工作,这很不幸。重新设计您的 ui 是唯一可以做的事情。
