After some hours of digging, I discovered why this small script
worked erratically:
[% USE q=CGI %]
[% a = q.param('xx') %]
[% a.push(3) %]
[% a.join(',') %]
it behaves differently if it is called as
1) http://myserver/myscript.tt2
2) http://myserver/myscript.tt2?xx=2
3) http://myserver/myscript.tt2?xx=2&xx=4
since q.param in the first case returns empty, in the second a scalar and
in the third a list. In this case it does not work in case 1,2
replacing the second line of the script with
[% a = q.param('xx').list %]
it works in case 2,3 and not in case 1.
The only way I find to have it working in all cases is to replace line 2
with
[% a=[]; FOREACH x = q.param('xx'); a.push(x); END %]
This should be written in the help pages.
Maybe there is a simpler way? Or should the "list" virtual method return
an empty list when called with a void argument?
