Okay, here is a complete tiny class that seems to exhibit the same  
behavior.  The counter increments when the anchor is clicked, but the  
value of selection is always nil.

Any ideas?


Smalltalk defineClass: #AsyncTest
	superclass: #{Seaside.WAComponent}
	indexedType: #none
	private: false
	instanceVariableNames: 'list selection counter '
	classInstanceVariableNames: ''
	imports: ''
	category: 'Run BASIC'!

!AsyncTest class methodsFor: 'as yet unclassified'!

	^ true!

	self registerAsApplication: 'asyncTest'.! !

!AsyncTest methodsFor: 'rendering'!

renderContentOn: html
	self renderOnHtml: html!


renderOnHtml: html
	| select anchor |
		text: 'Async test';
	(html form)
		id: 'testForm';
					text: 'Counter = ' , self counter asString;
				(html div)
					id: 'section';
							[select := html select.
							select list: self list.
							select on: #selection of: self.
							anchor := html anchor.
										[:h |
										self counter: counter + 1.
										self renderOnHtml: h];
								submitFormNamed: 'testForm';
								text: 'test'.
							html break.
							html text: self selection]]! !

!AsyncTest methodsFor: 'accessing'!

	counter isNil ifTrue: [ counter := 0 ].

counter: anObject
	counter := anObject!

	list isNil ifTrue: [ list := OrderedCollection with: '1' with: 'one'  
with: 'won' with: 'Juan' ].

list: anObject
	list := anObject!


selection: anObject
	selection := anObject! !

#{AsyncTest} initialize!
