Multipass Datasets doesn't work

Multipass Datasets doesn't work

[Martin Fechner]

Hello,

the simple example from the mailing-list doesn't work with the latest 
beta. I think the core-dat.lua is corrupted (function 
commands.datasetvariable)


\definedataset[test-1]
\definedataset[test-2]

\starttext

\setdataset[test-1][x=Value X 1,y=Value Y 1]
\setdataset[test-1][x=Value X 2,y=Value Y 2]

\setdataset[test-2][a][name=Ben Lee User,job=Manager]
\setdataset[test-2][b][title=TeX by Topic]

\startlines
\datasetvariable{test-1}{1}{x}:\datasetvariable{test-1}{1}{y}
\datasetvariable{test-1}{2}{x}:\datasetvariable{test-1}{2}{y}
\stoplines

Name: \datasetvariable{test-2}{a}{name} \par
Job: \datasetvariable{test-2}{a}{job} \par

\stoptext


Kind regards,

Martin

Change the following test in core-dat.lua:

function commands.datasetvariable(name,tag,key)
    local t = collected[name]
    if t == nil then
        if trace_datasets then
            report_dataset("unknown: name %s (not passed to tex)",name)
        end
    elseif type(t) ~= "table" then
        context(tostring(t))
    else
        t = t and (t[tag] or t[tonumber(tag)])
        if not t then
            if trace_datasets then
                report_dataset("unknown: name %s with tag %s (not passed to tex)",name,tag)
            end
-       elseif type(t) ~= "table" then
+       elseif type(t) == "table" then
            local s = t[key]
            if type(s) ~= "table" then
                context(tostring(s))
            elseif trace_datasets then
                report_dataset("table: name %s, tag %s (not passed to tex)",name,tag)
            end
        end
    end
end

Now it works, thanks.
