field Type no passing tag data to replace_tag function

Question

having a bit of a problem with a field type and trying to pass in tag data.:

in my template i have

{entries ...} {field} {keys}{key}{/keys}{/field} {/entries}

however when i do a var_dump($tag_data) in the replace_tag() function i am getting false.

however a var_dump($data) if producing the expected data in the same function..

Any Ideas?

Additional: i have already tried a tag pair in the same format as {myfield:option} Tag data here {/myfield}

You have to add the has_array_data property to your fieldtype class:

class My_field extends EE_Fieldtype {
  public $has_array_data = TRUE;

  ...
}
