 <instance of xowiki::Page> create_form_fields_from_form_constraints \
    [ -lookup ] form_constraints

Defined in packages/xowiki/tcl/xowiki-procs.tcl

Create form-fields from form constraints. When "-lookup" is specified, the code reuses existing form-field instead of recreating it. Since create_raw_form_field uses destroy_on_cleanup, we do not have to care here about destroying the objects.

Switches:

-lookup

(optional)

Parameters:

form_constraints

Returns:

potentially empty list of form-field objects
