Makes an hidden action.
Class HiddenAction( al, cmd, value ) from \
Action(( nil, al))
| al | The authorization level under which this action is ignored. |
| cmd | The command to be added to the form surrounding this action. |
| value | The value of the command. |
Hidden actions are never rendered, but they generate hidden input fields that can be a part of a global form.
If the value paramter is a function, the passed function is run before deciding to add this action rendering. If false, this action is ignored. If the function returns a string, the result is set in place of the value field.
Note: The cond function is called with the "eid" parameter of the @ HiddenAction.render method as first parameter, and with this same entity as second parameter.
