custom component controller is executed even though rendered=false

I have a visualforce page that has a custom component with rendered=false.  In a different pageBlockSection, I have an inlineEditSupport component.


The problem is that when the page loads, it executes the constructor and methods of the custom component's controller.   I wouldn't expect it to do that since rendered=false.

 

If I remove the inlineEditSupport component and reload the page, it does not execute the custom component controller.

 

How can I prevent my custom component controller from executing while keeping the inlineEditSupport on the page? Rendered=false does not seem to work.

 

Here is the (simplified) code:

 

1. Custom Component Controller

public class componentController {
	public List<account> accounts{
		get{
			system.debug('in accounts getter');				
			return new List<account>();
		}
		set;
	}
	public componentController(){
		system.debug('in constructor');
	}
}

 

2. Custom Component

<apex:component controller="componentController">
	<apex:pageBlockSection >
	    <apex:pageBlockTable value="{!accounts}" var="a">
	    	<apex:column >
	        	<apex:outputField value="{!a.name}"/>
			</apex:column>
		</apex:pageBlockTable>
	</apex:pageBlockSection>
</apex:component>

 

3. Visualforce Page

<apex:page controller="myController" tabStyle="Account">
    <apex:pageBlock >
        <apex:form >
            <apex:pageBlockSection >
                <apex:outputField value="{!account.name}" />
                <apex:outputField value="{!account.NumberOfEmployees}" />
                <apex:inlineEditSupport showOnEdit="saveButton, cancelButton" hideOnEdit="editButton" event="ondblclick"/>
            </apex:pageBlockSection>
            <apex:pageBlockSection columns="1">
                <c:editMode rendered="false" />
            </apex:pageBlockSection>
        </apex:form>
    </apex:pageBlock>
</apex:page>

 

When the above vf page loads, the debug log will include the "in constructor" and "in accounts getter" statements.  

If I remove the inlineEditSupport from the page and refresh, the debug log will not include those statements.

 

Any ideas?

I'm not sure "rendered" is a valid component tag attribute.  If you put the component reference inside an <apex:outputPanel > like below, you may get the result you're looking for.

 

<apex:outputPanel rendered="false">
    <c:editMode rendered="false" />
</apex:outputPanel>

"rendered" is a valid attribute.  See the docs.  Putting the component inside an <apex:outputPanel>  did not make any difference.  It still called the constructor and methods on the controller.  There is a similar question here.
