Martin Grigorov's comment from users-list:
"The page should be marked as stateless to avoid storing it."
> ComponentRenderer.renderComponent() adds a page to DataStore

> Key: WICKET-5422
> URL: https://issues.apache.org/jira/browse/WICKET-5422
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 6.12.0
> Reporter: Mateusz Mieszkowski
>
> I'm using ComponenetRenderer withing CustomTooltipBehavior (wicket-jquery-ui)
> to generate tooltip content. I add this to about 50 rows in my table so I run
> renderComponent() method as many times.
> All worked fine but there was a problem with performance when I used Fragment
> component with markup attached to the WebPage. I did some digging and finally
> checked http://localhost:8080/context/wicket/internal/debug/diskDataStore and
> it appeared that for one request, Wicket stores 51 pages in it. All of the
> size of the whole page (about 300kB) and all of them named
> org.apache.wicket.core.util.string.ComponentRenderer$RenderPage.
> I changed implementation from Fragment to Panel componenet and the size was
> reduced to (1kB) but still all of these items were stored in the DataStore.
> It seems that this method is creating a dummy page in order to create the
> markup, but how can I avoid storing these pages?
