Yeis.

I'll try.

first, this method creates the reading thread:
initializeThreading
	| ws |
	readProc _ [[(Delay forMilliseconds: 100) wait.
			ws _ WriteStream
						on: (String new: 4000).
			[socket dataAvailable]
				whileTrue: [ws nextPutAll: socket getData asString].
			ws size > 0
				ifTrue: [self processIncoming: ws contents.
					semaphore signal]] repeat]
				forkAt: Processor userInterruptPriority - 10

important here is processIncoming. it does this:

processIncoming: aString 
	"Check if the stream is closing (see checkIfClosingAndRepair), and then  
	put the data into its channels.  
	If it is closing, disconnect after processing."
	[snip]
	doc _ XMLDOMParser parseDocumentFrom: xmlString readStream.
	self assert: doc elements size = 1.
	el _ doc elements anyOne.
	el name caseOf: {
		[#stream:stream] -> [self verifyProtocol: el attributes].
		[#iq] -> [self channel: #iq add: el].
		[#stream:error] -> [self channel: #stream:error add: el]}
		 otherwise: [self error: el name asString , ' is unknown!'].
	closing
		ifTrue: [self disconnect]

disconnect btw calls terminate on its own process.

so, obviously, in every every case, the channels variable was modified before 
calling signal.

I read it like this:

authenticateName: name password: pwd resource: rsc 
	| el |
	self send: [snip authenticate me].
	semaphore wait.
	"(Delay forMilliseconds: 1000) wait." <-- uncommenting this brings it to work
	el _ (channels at: #iq) last.
	(el attributes at: #type)
			= #error
		ifTrue: [AuthenticationException
				signalWithQuery: (el firstTagNamed: #query)]

But even with incorrect password, the error doesnt arrive in channels fast 
enough to give an authentication exception.

hope i cleared it. i tried to make a shorter snippet to let it fail, but it 
worked fine there.

regards,

nick
