[Seaside] DNU in calculation of footer in WATableReport displays 'Request handling aborted; reload to retry'

[Yar Hwee Boon]

I'm getting a DNU (problem in my code) in WATableReport's footer  
calculation, specifically in #detectSum:. A DNU page is not returned,  
instead 'Request handling aborted; reload to retry' is displayed. Is this  
intentional? I can provide a reproduceable example if necessary. Thanks.

PS: I'm a little confused right now, excuse me if this is blantantly  
obvious...
