Hi,
The debug panel in wicket-devutils uses WicketObjects#sizeOf() to calculate
the size of the page and the session.
The "problem" that I see is that it calculates the size of the non-detached
object. I think what really matters is the size after detaching it, because
this is what is being saved in the http session and the disk, and I guess
this is what the developer needs to know actually.
Since #detach() can be called at any time, and several times per request
processing I suggest the following change:
---
a/wicket-core/src/main/java/org/apache/wicket/core/util/lang/WicketObjects.java
+++

Do you see any problems with this ?
