Question

我创建了这个隔离我的问题的测试用例。一旦轮询执行ajax更新，就不会执行a4j：commandLink操作。如果我们在轮询的reRender之前关闭modalPanel，则执行它。

有什么建议吗？提前谢谢。

TestBean.java

import org.apache.log4j.Logger;
public class TestBean {
private boolean condition1=false;
private boolean condition2=true;
private boolean poll=true;

public void close(){
Logger.getLogger("com.eyeprevent").info("here!");
poll=false;
condition1=true;
condition2=false;

}

public boolean isCondition1() {
return condition1;
}

public void setCondition1(boolean condition1) {
this.condition1 = condition1;
}

public boolean isCondition2() {
return condition2;
}
public void setCondition2(boolean condition2) {
this.condition2 = condition2;
}
public boolean isPoll() {
return poll;
}
public void setPoll(boolean poll) {
this.poll = poll;
}
}

TestBean是会话作用域。 Richfaces版本3.3.2.SR1

并且在Chrome 5.0.322.2 dev中也没有出现modalPanel。它在FF和IE7下完成。

Answer 1

尝试以下任意组合：

将<a4j:form>移到模态面板
将domElementAttachment（模态面板）属性设置为form或parent
尝试使用<h:form>

请尝试以下操作，而不是<a4j:commandLink>：

<h:graphicImage value="/images/modal/close.png" styleClass="hidelink"
            onclick="#{rich:component('examinationPanel')}.hide()" id="close" />

并在onhide="notifyClose()"上使用modalPanel，其中使用notifyClose()定义<a4j:jsFunction>。这是一种解决方法，但可能会有效。

这是可行的解决方案。我接受Bozho的答案是有效的，因为他提出了在这里实现的解决方法，但我只是在这里发布完整的解决方案以防任何人遇到同样的问题。

        </h:panelGroup>

    <a4j:form>
        <h:panelGrid columns="1" id="timeoutText">
            <h:outputText id="remainingtime" value="condition1" rendered="#{test.condition1}" />
            <h:outputText id="timer" value="condition2" rendered="#{test.condition2}" />
        </h:panelGrid>
        <a4j:poll id="poll" interval="5000" enabled="#{test.poll}" reRender="poll,timeoutText" />
    </a4j:form>
</rich:modalPanel>
</a4j:outputPanel>
<h:form>
<a4j:commandLink oncomplete="#{rich:component('examinationPanel')}.show()" reRender="testing">Link</a4j:commandLink>

    <a4j:actionparam name="param1" assignTo="#{test.poll}" />
</a4j:jsFunction>
</h:form>
</html>

将a4j:jsFunction保留在modalPanel标记之外非常重要。

TestBean.java：

import javax.faces.event.ActionEvent;
import org.apache.log4j.Logger;

public class TestBean {
    private boolean condition1 = false;
    private boolean condition2 = true;
    private boolean poll = true;

    public void close(ActionEvent event) {
        Logger.getLogger("com.eyeprevent").info("here!");
        poll = false;
        condition1 = true;
        condition2 = false;
    }

    public boolean isCondition1() {
        return condition1;
    }

    public void setCondition1(boolean condition1) {
        this.condition1 = condition1;
    }

    public boolean isCondition2() {
        return condition2;
    }

    public void setCondition2(boolean condition2) {
        this.condition2 = condition2;
    }

    public boolean isPoll() {
        return poll;
    }

    public void setPoll(boolean poll) {
        this.poll = poll;
    }
}

a4j：commandLink在reRender之后停止工作
