[Seaside-dev] #beAwareOfChangeOf:with:from: in WADispatcher

[Michel Bany]

Hi Lukas,

I believe/think the new Cincom Seaside integration doesn't need this  
functionality any more, so it is probably safe to remove it  
completely from Seaside 2.9, especially since the integration of  
Seaside 2.9 has not started yet. It is still needed in Seaside 2.8 by  
"my" port of Seaside. For your information, my port will be also  
available for 2.7 and 2.8 as a contributed in VW 7.6, in addition to  
the supported port of 2.8.

Cheers,
Michel.
