reRender and rendered attribute in visualforce

i write a visualforce page with source code

<apex:page controller="MyController1">
<apex:form>
<apex:pageBlock >
<apex:pageBlockSection  id="search">
<apex:commandLink action="{!commandLinkAction}" value="Advance Search"  reRender="thePanel" id="theCommandLink"/>
<apex:outputPanel id="thePanelWrapper">
<apex:outputPanel id="thePanel" rendered="{! rend}" layout="block">My div</apex:outputPanel>
</apex:outputPanel>
</apex:pageBlockSection>
</apex:pageBlock>
</apex:form>
</apex:page>

and the MyController1 class is

public class MyController1{
public Boolean rend{get;set;}
public PageReference commandLinkAction(){
rend=true;
return null;
}

}

when i click on Advanced Search link nothing happens but i was expecting outputPanel with id "thePanel" should render.why it is not rendering please someone explain??

I changed your code. check the code and see, are there your requirement?

 

<apex:page controller="MyController1">
<apex:form >
<apex:pageBlock >
<apex:pageBlockSection id="search">
<apex:commandLink action="{!commandLinkAction}" value="Advance Search"  reRender="thePanelWrapper" id="theCommandLink"/>
<apex:outputPanel id="thePanelWrapper">
<apex:pageBlock id="thePanel" rendered="{! rend}" ></apex:pageBlock>
</apex:outputPanel>
</apex:pageBlockSection>
</apex:pageBlock>
</apex:form>
</apex:page>

 

public with sharing class MyController1 {
public Boolean rend { get; set; }
public MyController1 ()
{
rend = false;
}

    

    public PageReference commandLinkAction() {
    rend = true;
        return null;
    }

}

Change the rerender to this id instead:

thePanelWrapper

rerender should always be to an outputpanel with NO rendered on it
