A co-worker inherited a TWiki table with inappropriate header/footer parameters. I don't dispute the bad parameters, but the error, in this case, was overly opaque.

Given this configuration:

%TABLE{sort="on" headerrows="2" footerrows="1"}%
|*Country*|*Total*|*%*|*Space ID*|

Clicking the Edit button produces the following error page:

TWiki detected an internal error - please check your TWiki logs and webserver logs for more information.

Modification of non-creatable array value attempted, subscript -1

Fixing the TABLE parameters to have 1 headerrow and no footerrows make the error disappear.


Country Total % Space ID
aa 7,316 71.06% 800

Bug confirmed. Thanks Vicki for the report.

Range check on actual number of rows needs to be done.
