Need to add the custom action to the parent actions holder (such as
onentry, onexit or transition). So, minimally, you'll have to add the
SetNextRule (and maybe others, as per your action needs):
digester.addSetNext("*/custom/command", "addAction");
As an aside, best to add custom actions to these three paths (where
ACTION_NAME is name of the custom action element):
"!*/onentry/" + ACTION_NAME
"!*/transition/" + ACTION_NAME
"!*/onexit/" + ACTION_NAME
