Hello,

The userFieldValue() apparently works fine with the current standard, i.e. the OpenDocument format (ODT, ODS, ODP files and so on), but it doesn't correctly support the old OpenOffice 1.0 format (SXW, SXC, SXI, etc). Up to know, this bug was unnoticed because the SXW format was already deprecated when OpenOffice::OODoc 2.1x got out (2008), so nobody complained in this forum.

As a possible immediate workaround, you can convert your SXW document(s) into ODT then check if everything goes right with OODoc 2.111 (please let's know if it works). For later, knowing that the bug has been reported in the tracker (#54004), I'll try to fix it in the future release.
