Hi all, I can’t explain the following behavior of the .tuc writer. When passed a nested hash, context fails on the second pass if the array part of the first nesting depth is empty: ······································································· %% the commented lines work \startluacode job.variables.tobesaved.foo = { bar = { } } -- job.variables.tobesaved.foo = { "works now", bar = { } } -- job.variables.tobesaved.foo = { bar = "works too" } \stopluacode \starttext foo \stoptext ······································································· I get this error: ······································································· !
