你好我是新來的在這裏在stackoverflow我使用的是primefaces 3.5我的問題是,是否有必要在靜態塊或構造函數中設置selectonemenu項目(Java util的Map).. like:無法在primefaces中生成selectonemenu項目
slider.xhtml
<h:outputLink value="circle">
<h:outputText value="click Circle!"/>
</h:outputLink>
漂亮-config.xml中
<url-mapping id="circle">
<pattern value="/circle" />
<view-id value="xhtmls/circle.xhtml" />
<action>#{circleAction.action}</action>
</url-mapping>
CircleAction.java
public class CircleAction {
private String favCoffee2;
private Map<String,Object> coffee2Value;
//setter n getter
public Map<String,Object> getFavCoffee2Value() {
return coffee2Value;
}
public String action(){
coffee2Value = new LinkedHashMap<String,Object>();
coffee2Value.put("mohsin - Cream Latte", "Cream Latte"); //label, value
coffee2Value.put("mohsin - Extreme Mocha", "Extreme Mocha");
coffee2Value.put("mogsin - Buena Vista", "Buena Vista");
return "pretty:addcircle";
}
}
circle.xhtml
<p:selectOneMenu value="#{circleAction.favCoffee2}">
<f:selectItems value="#{circleAction.favCoffee2Value}" />
</p:selectOneMenu>
selectOneMenu用於在這種情況下,空白,但是當我從操作方法去除下面的代碼,並將其放置在靜態塊吧selectOneMenu用於將產生在java.util中的所有項目。地圖;
coffee2Value = new LinkedHashMap<String,Object>();
coffee2Value.put("mohsin - Cream Latte", "Cream Latte"); //label, value
coffee2Value.put("mohsin - Extreme Mocha", "Extreme Mocha");
coffee2Value.put("mogsin - Buena Vista", "Buena Vista");
那我該怎麼辦?我 h:outputLink> –

那我該怎麼辦?我有其中我想調用處理一些數據並將其呈現給SELECTONEMENU的'ACTION'方法,因爲之前我做過一個表單,我選擇了一些值並提交' {circleAction.edit}該值爲同一類(CIRCLE ACTION)但編輯()方法,但它不工作,因爲當我點擊我的瀏覽器URL是http:// localhost/myApp /調用URL後調用#{circleAction.ation}的循環是http:// localhost/myApp/addcircle,但是selectOneMenu不是wrking, –

如果我使用URL localhost/myApp/circle,它總是調用操作方法,但我也想調用編輯方法 – 2013-03-20 15:37:28
