I have a class I use to manage collections of aggregated objects. I'm trying to use it with the -Class parameter option and instforwarding so that I can do things like this:
Test x x apples add Z x apples items*That* part I can get to work as expected. But I can't get the default option of instforwarding to work for this case:
x apples
Michael,
the default values are only used in te substitution of %1, which refers to the first argument of the invocation. The default ist used, whenever the argument is not specified in the invocation. So, essentially, the %1 was missing in your example (see below)

=================================
Test instforward apples -default {items add} {%my _apples_} %1 Test instforward oranges -default {items add} {%my _oranges_} %1
Test z z apples new TestItem z apples new TestItem
# no arguments, use default puts [z apples]
Class GoldenDelicious GoldenDelicious apple1 GoldenDelicious apple2
# explicit add z apples add apple1
# implcit add (via default) z apples apple2
puts [z apples] =================================
