xowiki::FormPage instproc set_property (public)

 <instance of xowiki::FormPage> set_property [ -new new ] name \
    value

Defined in /var/www/openacs.org/packages/xowiki/tcl/xowiki-procs.tcl

boolean flag telling if the property is new. Setting a value on a non-existing property without specifying this flag will result in an error.

Parameters:

value (required)

property value

Returns:

value (eventually converted to a has-notation message key)

Testcases:

create_form_with_form_instance

Source code:

if {[string match "_*" $name]} {
  set key [string range $name 1 end]

  if {!$new && ![info exists :$key]} {
    error "property '$name' ($key) does not exist.  you might use flag '-new 1' for set_property to create new properties"
  }
  set :$key $value

} else {

  if {!$new && ![dict exists ${:instance_attributes} $name]} {
    error "property '$name' does not exist.  you might use flag '-new 1' for set_property to create new properties"
  }
  dict set :instance_attributes $name $value
