如何在h：selectOneMenu中执行值变化转换？
通常我会做类似下面的事情。单击按钮执行转换。
<!-- view -->
<h:form>
<h:commandButton action="doit">
<f:ajax render="@form"/>
</h:commandButton>
</h:form>
<!-- flow -->
<transition on="doit">...</transition>
<h:form>
<h:selectOneMenu value="#{selected}">
<f:selectItems value="#{items}/>
<f:ajax event="valueChange" render="@form" />
</h:selectOneMenu>
</h:form>
<h:form>
<h:selectOneMenu value="#{selected}">
<f:selectItems value="#{items}/>
<f:ajax event="valueChange" render="@form" listener="#{bean.changeListener}" />
</h:selectOneMenu>
</h:form>
import javax.faces.event.AjaxBehaviorEvent;
import org.springframework.webflow.execution.Event;
public class Bean {
public void changeListener(AjaxBehaviorEvent event) {
// prepare webflow event
Event e = new Event(event.getSource(), "doit");
// propagate this event... ???
}
}

public void changeListener(AjaxBehaviorEvent event) { RequestContext requestContext = RequestContextHolder.getRequestContext(); RequestControlContext rec = (RequestControlContext) requestContext; //place variables you need in next flow phase here; flash,application,session scope rec.getFlashScope().put("someVarIneedInNextFlow", varName); rec.handleEvent(new Event(this, "flow transition name here, i.e. next-stage")); return; }
