namespace support for f:table

the f:table tag does not have a namespace attribute so it is impossible to generate a table where the column sorting and links to CONTROLLER/show respect the namespace... [EDIT] unless I use the nifty (yet undocumented) template trick described in issue grails/fields#203

Start by locating the f:table tag implementation and examining how its column sorting and CONTROLLER/show links are generated. Review the template technique described in grails/fields#203, then define completion as namespace-aware sorting and links without requiring that workaround.
