Playing with [bpatcher] with javascript

Hi there,

I'd need to know if there would be a smooth solution to manipulate bpatchers with JS.

Indeed, I'm creating bpatcher, "filling" them with a patch and it gives errors in Max window BUT it works. So these errors drive me to say I could make a mistake or what.

var myObject = this.patcher.newdefault(x, y, "bpatcher", "@varname", "name" + z, "@presentation", 1);
myObject.replace("/Users/julien/DATA/baptchers/myPatch.maxpat");

Something else, message to bpatcher.
I knew about sendbox messages to [thispatcher], also about message() function to object from JS.

But what should I do in the case where I don't have any connection to my bpatcher ?

Actually, I don't want to connect them and only want to control their creation/move etc using JS.

Is there a smooth way ?

I tried:

myObject.patching_rect(x +"400 100 100");

and also

myObject.message("patching_rect", x +"400 100 100");

No luck with those.
