Sending messages using javascript

Hey all, I am trying to insert data into a coll via
js but have not been able to get it right. Can some
one take a quick look at this and help me figure out
what I am doing wrong.

Thanks,
Anthony

Should be:

mobj.message(1, "somedata");

because coll expect a list with the first argument which should be an
int followed by any number of argument (separated by comas in your js,
unless you provide an Array).

I see, that is really confusing…

One other thing, why does the following statement not work…

messnamed ("testcoll", 1, "somedata");

Thanks,
Anthony

Well it does work, but not the way you probably expect ;-) It send the
list [1 somedata] to a receive called testcoll.

Ahhh, I see. I thought you could use messnamed
for any named object. Good to know, thanks.

Just so that I am sure, are send/rcv objects the only things
I can use messnamed for?

no, it works for all named objects…

your example works, but you have to respect what the coll object
understands.
the anything message doesn’t trigger any storage action.
use the "store" message to store a ‘list’ that begins with a symbol
(an "anything" type), otherwise send a ‘legal’ list, where the first
element is the key.

just to make it clear, messnamed() only send messages to receives
objects. For any object you can use the message() method for a MaxObj
as Jan showed.
