Re: Dynamic Custom Fields

[Jorge Arturo Tijerina García]

While digging into the file detail, I realize that the blank page appear
only when I "extend" the Dynamic_Custom_Field_Backend class from my
customized class file.
If I do not extend the class, the only thing I get is de list of options I
delcared in the array inside of the getStructuredData() function:

function getStructuredData()
   {
       return array(
              array(
                 "keys" =>   array("Procesos"),
                    "options"   => array(
                                 "auditoria" =>  "Auditoria",
                                 "modelado"  =>  "Modelado",
                                 "calidad"   =>  "Calidad"
                               )
                  ),
               array(
                    "keys"  =>  array("Arquitectura"),
                    "options"   =>  array(
                                 "framework" =>  "Framework",
                                 "ealib" =>  "EALib"
                               )
                  )
             );
   }
based on the file documentation, "keys" elements must match the
"controlling" field (master combo) and the "options" elements are displayed
in the "child" combo that depends on the master selection, but.. my question
is, where did I define the change event of the master combo?, How do I
relate the master combo with the child combo (subordinate)?. I set up only
one class file with these options but it seems doing nothing at all ...

Please advise.

PS. No error log is generated...
