Keith --
I was trying out your MADivsRenderer this evening and found that if my
description class has no cssClass specified, that the following causes
problems when the call to "(self classFor: aDescription)" returns
nil.. It then tries to append "clear" to the list and that gets me a
DNU.. It took me a while to track it down as I initially thought it
might be a general Migritte issue.. Anyway,
MAComponentRenderer>>classFor: has a call to #reduce at the end and if
the class list is empty it returns nil which is where the initial nil
is coming from. I checked to see what Squeak has for the #reduce:
method and it also returns nil when the OrderedCollection is empty --
so this bug should be reproducible on Squeak as well..
I suppose one work-around would be to change
MAComponentRenderer>>classFor: to check if it gets nil back from the
reduce call and not return a nil object or perhaps something else like
changing MADivsRenderer>>renderContainer to check the return value of
#classFor: to see if it gets a nil back and if so create a string
object....
comments/suggestions welcome..
