Hi,
that could be the same issue mentioned some time ago on the list regarding
output of udat or using functions like substr in [+ +] blocks. Maybe Readonly
does some magic in the background.
Please look at the archive for more information.
Our fix: [+ do { $udat{foo} } +]
With best regards,
Dirk Melchers
