標記:奇怪的行爲
<h:head>
<title>title</title>
</h:head>
<h:body>
<h:form>
<h:outputText value="#{viewScopeBacking.date}">
<f:convertDateTime timeZone="#{viewScopeBacking.timeZone}"/>
</h:outputText>
<h:commandButton action="#{viewScopeBacking.action}" value="submit">
<f:ajax event="action" render="op"/>
</h:commandButton>
<h:outputText value="#{viewScope.view}" id="op"/>
</h:form>
</h:body>
</html>
支持bean:
@ManagedBean
@RequestScoped
public class viewScopeBacking {
public viewScopeBacking() {
}
@ManagedProperty(value = "#{viewScope}")
Map<String, Object> viewMap;
private Date date = new Date();
private TimeZone timeZone = TimeZone.getDefault();
public void action() {
getViewMap().put("view", "hello world");
}
//getters and setters
public Date getDate() {
return date;
}
public void setDate(Date date) {
this.date = date;
}
public TimeZone getTimeZone() {
return timeZone;
}
public void setTimeZone(TimeZone timeZone) {
this.timeZone = timeZone;
}
public Map<String, Object> getViewMap() {
return viewMap;
}
public void setViewMap(Map<String, Object> viewMap) {
this.viewMap = viewMap;
}
}
在按下按鈕時,應的outputText理論進行更新。但是,除非您刪除convertDateTime的timeZone屬性,否則不會發生這種情況。
這是如何[java] **和** [c] **和** [.net]? – 2010-11-11 13:25:25
這是Java(JSF 2.0) – siva636 2010-11-11 13:51:25
但您將C和NET添加到標籤。在這個問題中他們沒有任何意義,所以Marc刪除了它們(並且我用JSF標籤替換了JSP標籤,因爲根本不使用JSP,而是Facelets) – BalusC 2010-11-11 13:53:46
