It seems that assign.point: thing is related to accessor method point:
but if I have to create it everytime ThingLab is very hard to use one.
Instead, I fixed(patched) following

!Object methodsFor: '*ThingLab-message handling' stamp: 'NeXT 4/16/2007
08:12' prior: 33693109!
getFieldsForKeywordSelector: sel
	"sel should be of the form part1.subpart: part2.subpart.subsubpart: part3:
	 check that I have subparts of the appropriate names.  If so, return
	 a collection of arrays of Fields matching the keywords in sel;
otherwise return nil"
		|  fields arrayOfFields |
	arrayOfFields _ OrderedCollection new.
	sel keywords do:
		[:k | k size == 0 ifTrue: [ fields _ nil ] ifFalse: [
		fields _ self getFieldsForPath: k pathFromDottedSelector.].
		fields isNil
			ifTrue: [^nil]
			ifFalse: [arrayOfFields add: fields]].
	^arrayOfFields! !

(Sorry for bad indentation, I don't know why) The problem I tried to fix
is that sel keywords does have '' as its last element which causes
error. So, I ignore it. :-)

With above patch it seems that ThingLab does work.

Thanks.
