Seaside 3.2: WAUrl absolute: signals primitiveFailed

Hi there,


I am trying to port a Seaside Application from VA Smalltalk 8.6. to 
8.6.3. That includes porting from Seaside 3.0 (?) to Seaside 3.2.

After some troubles with addLoadScript:, which needed documented 
changes, I now am at a point where most of my Ajax callbacks don't work.
I debugged a little and found out that the callbacks really aren't found 
in the callback registry.

The reason seems to be WAUrl which parses URLs incorrectly. At least I 
think so.

Please try this in your image:

WAUrl absolute: 
'/Buchhaltung?_s=F4N82ZReQEV2M1cP&_k=spf8TDq4kzHfrPCi&48&searchText=kas'

(48 is the key of my Ajax callback, as you might have guessed)


This works in VA Smalltalk 8.6 and in Pharo 5 with Seaside 3.0.

# In VAST 8.6.3 it yields a strange result:

   The queryFields of the resulting WAUrl have the following keys: ('_s' 
'_k' '48&searchText' 'searchText' nil nil)

  -->  That seems to be definitely wrong!!! The keys should be ('_s' 
'_k' '48' 'searchText' nil nil)

# In Pharo 5 with Seaside 3.2, the above expression yields a debugger 
with a primitiveFailed Error, because it tries to create a ByteString of 
Size -12.


So WAUrl parses the callback (48) wrongly


Here is what I loaded into Pharo 5 (50770):

Metacello new
     configuration: 'Seaside3';
     repository: 
'http://www.smalltalkhub.com/mc/Seaside/MetacelloConfigurations/main';
     version: #'release3.2';
     load.


Is this a known issue? Is there a fix for it? Has the logic for 
registering and finding callbacks changed between 3.0 and 3.2, so do I 
have to change my javascript code that issues ajax callbacks?


Thanks for reading,

Joachim
