How do I hide a component on some layouts but still perform work?
I have a component that we only show on some layouts for an object. It has a polling function that monitors changes to the object (an object from a managed package). One function of the polling is to refresh the page when some custom field values change.
I need this refresh functionality now on all layouts for this object, but I do not want to display anything on the actual page in the layouts that do not need it.
What I have tried is to put a public boolean on the controller that says whether or not to render the controls. What this does is hide the controls but leaves a large white space on the page where the controls would be. Of course I do not want this space to show.
Here is a simplified version of my page :
Any ideas on what I could do differently?
I am a (c#, c++, JavaScript...) developer, but have only been writing apex code on the salesforce platform for about 8 months, so I realize I may not be headed in the right direction.

<apex:outputPanel rendered="{!refreshQuoteNow}">

window.top.location='/{!quoteID}';

</apex:outputPanel>
<apex:pageBlock id="metrics" rendered="{!showCustomComponent}">
</apex:pageBlock>
</apex:form>
</apex:component>

1.) using the showCustomComponent in the rendered tag for apex:component
or
2.) still use your pageblock but set everything else inside it (form, actionpoller, etc) To where pageblock is a direct child element of the component.
Another way I could do it is to split this into 2 components - is there a way to have a component take 0 space?
