Page parameters don't work when using rendered

Hey

Can anyone help me understand why using page parameters don't work when using rendered?

 

I've tried this, which only works if I remove the rendered  property from the outputPanel: 

<apex:page standardController="Parent__c" >
    <apex:pageBlock title="Children for {!Parent__c.name}">
        <apex:form >
            <apex:pageBlockTable value="{!Parent__c.Children__r}" var="child">
                  <apex:column headerValue="Name" >
                      <apex:commandLink rerender="detail"> 
                          {!child.Name}
                          <apex:param name="cid" value="{!child.id}"/>
                      </apex:commandLink>
                  </apex:column>
            </apex:pageBlockTable>
        </apex:form>
    </apex:pageBlock>
    <apex:outputPanel id="detail" rendered="{!$CurrentPage.parameters.cid!=''}">
        <apex:detail subject="{!$CurrentPage.parameters.cid}" relatedList="true" title="false" relatedListHover="true"/>
        ...some other stuff...
     </apex:outputPanel>
</apex:page>

 I hope anyone can help me get a bit wiser, thanks

You are doing rerender and render in the same panel.

Try this in separate panel

 

<apex:page standardController="Parent__c" >
<apex:pageBlock title="Children for {!Parent__c.name}">
<apex:form >
<apex:pageBlockTable value="{!Parent__c.Children__r}" var="child">
<apex:column headerValue="Name" >
<apex:commandLink rerender="detail">
{!child.Name}
<apex:param name="cid" value="{!child.id}"/>
</apex:commandLink>
</apex:column>
</apex:pageBlockTable>
</apex:form>
</apex:pageBlock>
<apex:outputPanel id="detail">
<apex:outputPanel rendered="{!$CurrentPage.parameters.cid!=''}">
<apex:detail subject="{!$CurrentPage.parameters.cid}" relatedList="true" title="false" relatedListHover="true"/>
...some other stuff...
</apex:outputPanel>
</apex:outputPanel>
</apex:page>
