少し奇妙なことですが、スピナーが機能していました。
<p:spinner min="1" max="1000" value="#{printerSettings.t}" size ="1">
<p:ajax update="NewTime"/>
</p:spinner>
<h:outputText value="#{printerSettings.getNewTime()}" id="NewTime"/>
これは毎回1ずつ上がり、ajaxは正常に機能しています
これはサーバー側のJavaコードです:
public int getT() {
return (t);
}
public void setT(int t) {
this.t = t;
}
私が知りたいのは、tの最終値をどのように保存できるかということです。この値を別のクラスで使用したいので、試しました。
t = ((new PrinterSettings().getT()) * 60);
クラスではtを使用したいのですが、スピナーから残っている値ではなく、常に1を取得します。
この問題を解決するにはどうすればよいですか
編集:
@ManagedBean
@RequestScoped
public class PrintInTen {
private int t;
public void tValue(int t) {
this.t = t;
System.out.println("My t value : " + t);
}
public void countDown() {
tを送信しようとしているBeanです
私はそれを上に送るためのボタンを作成しました:
<p:commandButton actionListener="#{printInTen.setTValue(printerSettings.t)}" value="Set Val" />
しかし、私はエラーが発生します:unknown property setTvalue
私はここで正しい線にいますか?どうすればそのエラーを解決できますか
このエラーが発生する
