This happens when you don't have Comanche installed when you first try 
to "start" WAKom.  So, if you haven't already done so you need to 
install the Comanche framework ("Kom"?) then you need to fix the class 
instance variable in WAKom which is improperly initialized.  Inspect 
WAKom and select the service variable.  Change its value to nil and 
accept the change.  Then try your "WAKom startOn: 9090" again.

Avi, this bit me as well as several other users.  I suggest the 
following change:

createService
    Smalltalk at: #HttpService ifPresent:
        [:hs |
        ^ (hs on: port named: 'seaside') plug: self default].
    Smalltalk at: #ComancheNetService ifPresent:
        [:cns |
        ^ (cns named: 'seaside' onPort: port) module: self default].
    self error: 'Comanche is not installed.  Install Comanche from 
SqueakMap and try again.'

to head off the problem.
