public class DialogFreemarker
extends DialogBox

A Magnolia dialog that renders by a freemarker template. There are two main properties for the dialog:

path (required) Path to freemarker template: will be loaded from classpath or from filesystem
multiple true / false. This property gives support to multiple field values storage.
The dialog passes some parameters to freemarker template:
name Dialog / field name
value Field value (multiple = false)
values field values (multiple = true)
request current HttpServletRequest
configuration Map of dialog configuration. This allows to pass to template complex dialog configuration.
Eg.
 -+ Dialog node
  |-- property 1 = value 1
  |-+ subnode1
  | |-- property 11 = value 11
  | |-- property 12 = value 12
  | |-+ subnode 11
  |   |-- property 111 = value 111
  |
  |-- property 2 = value 2

 The map will contain:
 configuration = Map {
    "property1" = "value1",
    "subnode1"  = Map {
        "property11" = "value11",
        "property12" = "value12",
        "subnode11"  =  Map {
            "property111" = "value111"
        }
    },
    "property2" = "value2"
 }
