Wolfgang

This example fails for me using the current (2014-09-27) standalone beta and with TL14. The failure is that the list of authors is presented as a grid without contents.

Changing any of the lines in the example that construct the table cells, such as
\bTD \structureuservariable{author} \eTD=
to
\bTD xx \structureuservariable{author} \eTD
results in a table with the new text, but no user variable text, showing that the \structureuservariable commands are not returning any text in this example.

Has something relevant changed since the example was prepared (2010-11 or earlier)?

(A pointer to useful descriptions of \structureuservariable and \structurelistuservariable would also be welcome. In the wiki, the startsection command description describes the former, but I have come across no comprehensive description for either in the documentation.)

First you have to make a distinction between the values which are set with the first and second argument of \startchapter, \startsection etc. =C2=A0While the first argument takes only cert= ain keys, e.g. title, bookmark etc. you=E2=80=99re free to choose you= r own keys for the second argument because they are considered userdata. =C2=A0The point of this userdata is to give users a way= to specify information which are printed in the table of content or in the header, to access these values context provides two commands. =C2=A0When you create a new layout for the table of contents you can use the \structurelistuservariable command which takes the name of the key with the information as argument and when you create a new header layout you can use the \structureuservariable command.

Thank you, Wolfgang, for that explanation.

Can you suggest what might be wrong with the example at http://wiki.contextgarden.net/Generate_Authorlist_from_Head_Content?

The list of authors is created, so the user variable 'author' is set at for \doifsomething. When the index for the author list is set to a constant, only one row is generated, but when it is the user variable 'name' the right number of rows is created, so 'name' is also set when it is referenced as the key in the author list sorting macro. Each line of the table is empty, suggesting that within the scope of the table the user variables are reset to nil. The same problem exists when \starttabulate is used instead of \bTABLE.
