Question

我正在尝试在处理ajax事件时禁用组合框，但是它将空值（而不是所选值）发送到bean setter。一旦我删除了代码onstart =“ PF（'testA'）。disable（）;”，它就会发送正确的值。

有人对此有解决方案吗？谢谢。

我正在使用Primefaces 6.2，JSF2.2，Java 7和Glassfish 4.1。

            <h:outputText id="themeId" value="#{selectOneMenuViewA.theme}"/>
    </h:form>
</h:body>

public class SelectOneMenuViewA {

private String theme;   
private List<String> themes;

@PostConstruct
public void init() {        
    themes = Arrays.asList("a", "b", "c");
}

public String getTheme() {
    return theme;
}

public void setTheme(String theme) {
    this.theme = theme;
}

public List<String> getThemes() {
    return themes;
}
}

在ajax事件期间禁用p：selectOneMenu的问题
