Mirror columns, rating columns, and formula columns do not work when referenced in a workdoc column.
Myself, and several accounts I work with would like mirror columns, and formula columns to function correctly when using a workdoc column template.
Currently mirror columns and formula columns are selectable when using the “column values” feature in workdocs. However, when using a mirror or formula column, the summary of that column shows incorrectly. If the columns has to use more than one datapoint, such as a mirror column, it will show each point of data individually, instead of showing the correct summary (Such as average or sum) that is selected in the column. Also, Formula columns that reference mirror columns show “No Value” instead of the correct output.
example below:
Mirror columns and formula columns are a very common use case for work doc templates as the user can easily create a report from a template and export to PDF from that workdoc template. Currently however this feature is unusable, when mirroring information from subitems, other boards, or using formulas.
I have created this as a bug report, but was asked to post it here instead.
I hope this helps, and I hope other users can confirm they are attempting to use this feature for workdoc columns and templates.
