Greetings all,
I've found the problem: In setVariables(), the command
vars.Add("PAGEHEADER", new String(config->Find("page_list_header")));
is executed before the command
vars.Add("PAGELIST", str);
That means that ${PAGELIST} is expanded as empty when the string is
created.
Swapping the order of these solves the particular problem, but the
more fundamental problem is that any variable can (or should be able
to be) defined in terms of any other, and there is no ordering which
can allow that. One possibility would be to go through and set each
variable *twice*, so that second time around, most variables should
have their right values. Of course, chains of variables defined in
terms of each other would need more than two iterations...
Another option would be to merge vars with config so that the
literal string ${PAGELIST} would be added, and only evaluated when
the variable is finally expanded during output.
Cheers,
Lachlan
