as in any prodedural language a function as argument gets immediately
executed so you need to delay:
context.startplacefigure({title = "Figure"})
context.startcombination({nx = "2", ny = "2"},
context.delayed.externalfigure({"cow"},{width = "50mm"}),
"Caption 1",
context.delayed.externalfigure({"cow"},{width = "50mm"}),
"Caption 2",
context.delayed.externalfigure({"cow"},{width = "50mm"}),
"Caption 3",
context.delayed.externalfigure({"cow"},{width = "50mm"}),
"Caption 4"
)
context.stopcombination()
context.stopplacefigure()
(this is why encoding complex documents completely in a scrtipt language
is non trivial and why for instance these template systems are there
because these accumulate)
