Everything works fine with fewer \items. Does that mean it does not support when there are too many rows? or continues to a second page?
I got the warning:
)
! Undefined control sequence.
\GenericError ...
#4 \errhelp \@err@
! LaTeX Error: Counter too large.. And if you look at the PDF produced by the example in your question it is also quite obvious :) You can also load packagealphalphand telltasksto use it:\NewPatternFormat{aa}{\alphalph}and thencounter-format={tsk[aa])}– cgnieder Dec 07 '15 at 20:47! Undefined control sequence.is not a warning message but an error message (LaTeX distinguishes between those) – cgnieder Dec 07 '15 at 20:48Undefined. All was defined perfectly. That to me was just confusing. Thanks about the other suggestion. – Chen Stats Yu Dec 07 '15 at 20:58
