Hi Hans,
the save/restore state for the counter in the example is ignored.
%%%% begin example
\enabletrackers[structures.counters]
\definecounter[test]
\starttext
\incrementcounter[test]
\convertedcounter[test]
\dorecurse{10}
{\savecounter[test]
\incrementcounter[test]
\convertedcounter[test]
\restorecounter[test]
\par}
\stoptext
%%%% end example
The problem is the check for the table size in the counters.restore
function because after the first save the size of the table is 1:
function counters.restore(name)
local cd = counterdata[name]
if not cd then
report_counters("invalid restore, no counter %a",name)
return
end
local saved = cd.saved
if not saved then
-- is ok
elseif #saved > 1 then
should be > 0
cd.data = remove(saved)
else
report_counters("restore without save for counter %a",name)
end
end
