A_DEFER_LOW

[panaiotis]

I'm trying to use A_DEFER_LOW in the class_addmethod declaration. This is how it is defied in the ext_mess.h file:
A_DEFER_LOW = 0x43, ///< A special signature for declaring methods. This is like A_GIMME, but the call is deferref [sic] to the back of the queue.

This is how I used it:
class_addmethod(p_iclass, (method) pFpu_msg_set_pos, "pos_", A_DEFER_LOW, 0);

This is how my function is prototyped:
void pFpu_msg_set_pos(pt_patch_mxa p_pmxa, t_symbol *s, long argc, t_atom *argv);

This is what I get when the "pos_" message is sent to the external, which is a UI object.
unknown message argument type
patchUtils: bad arguments for message "pos_"

What am I doing wrong? (I also tried A_DEFER with the same result.)
I tried fixing the misspelling of deferred (from deferref) but without change :)
