at the moment i have a very basic problem using embedmessage inside a save() function within the js and jsui object.

i attached a very simple path to illustrate my problem. a variable is set inside a jsui object an when receiving a bang it is posted to the max window.

when try to save the current value using the embedmessage and the save function the following error message will appear and the value of the variable will not be stored:

"js: embedmessage must be called within save function"

it is the same reaction using both object js and jsui and on OS X and Win XP.

currently i am using Max 5.0.7 (38327) on win XP and 

the javascript code is here: am i doing something wrong or is that a bug? I thought i was following the js/jsui API precisely ...

autowatch = 1;

var amount = 1;
var n = box;
function msg_int(a)
    {
    amount = a;
    post("amount", amount,"n");
    save();
    }

function bang()
    {
      post("amount", amount,"n");
    }

function save()
    {
    embedmessage("reload", amount);
    }

function reload(a) 
    {
    amount = a;
    }

You're calling save() from the msg_int() method which is not permitted. The save() function will be called automatically when you save the patcher. If you want to save multiple states you might want to use notify() + setvalueof/getvalueof to store states of your object with pattr. Hope it makes sense.

thank you very much for the clarification. the solution with pattr is indeed elegant. but as far as i understood that object until now i would need one pattr for each jsui object that i use. is that right? I work with 3 values for each jsui object and a various, dynamically generated number (many objects) of jsui.

wouldn't that mead that i i gerenrate a new jsui i would have to generate also a new pattr?

therefore i was thinking about writing all the values in a serialized text file and to parse them out when the patch is loaded.not so slick but it would have the advantage that i could export and archive the settings.

c'etait le bonne idee. Somehow i didn't thought about that.
