a4j:commandLink在重新渲染后停止工作 [英] a4j:commandLink stops working after being reRender
问题描述
我创建了这个测试案例，隔离了我的问题.一旦轮询执行ajax更新，就不会执行a4j:commandLink操作.如果我们在重新渲染民意调查之前关闭modalPanel，则会执行该操作.
I have created this test case that isolates my problem. The a4j:commandLink action is not executed once the poll does an ajax update. It is executed if we close the modalPanel before the reRender of the poll.
有什么建议吗?预先感谢.
Any suggestion? Thanks in advance.

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是会话作用域的. Richfaces版本3.3.2.SR1
TestBean is session scoped. Richfaces version 3.3.2.SR1
而且在Chrome 5.0.322.2 dev中也不会出现modalPanel.在FF和IE7下都可以.
And also in Chrome 5.0.322.2 dev the modalPanel does not appear. It does under FF and IE7.
推荐答案
尝试以下任意组合:
- 将
<a4j:form>移动到模式面板之外 - 将(模式面板的)
domElementAttachment属性设置为form或parent - 尝试使用
<h:form>
- move the
<a4j:form>outside the modal panel - set the
domElementAttachment(of the modal panel) attribute to eitherformorparent - try using
<h:form>
请尝试以下操作，而不要使用<a4j:commandLink>:
Try the following instead of <a4j:commandLink>:
<h:graphicImage value="/images/modal/close.png" styleClass="hidelink"
onclick="#{rich:component('examinationPanel')}.hide()" id="close" />
，并在modalPanel上使用onhide="notifyClose()"，其中notifyClose()是使用<a4j:jsFunction>定义的.这是一个变通办法，但可能有效.
and use onhide="notifyClose()" on the modalPanel, where notifyClose() is defined using <a4j:jsFunction>. This is a bit of a workaround, but might work.
