Thanks again Gustaf,
I've got another scenario to use list::create -pass_properties.
It works very well.

...
list::create \
-name events \
-multirow events \
-pass_properties { admin_p } \
...

Gustaf,

Instead of list::create, wouldn't the best place be in the db_multirow?

Or even, the switch pass_properties could be in both. Couldn't it?

The flag is especially for variables used in the list template, which are NOT part of the multirow (or db_multirow). The template::list iterates of the multirow tuples and needs the information, what other variables have to be provided in the "display_template".

Without looking at the details, it might be possible to modify the implementation of "display_template" to include all global variables, but - maybe for a good reason - this was not done at the first place.
