-------------------------------------------
Summary: 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?
