it’s the value that is not working in your example I think
you have to use attr
@roemhildtg
let a = can.DefineMap.extend('a', {
init(){
console.log(arguments);
},
val: {
set(val){
console.log('hey there', val);
return val;
}
}
})
let b = new a();
b.val = 'Hello';
console.log(b.val)
that does what you’re expecting
can-map and can-map-define are legacy modules
for backward compatibility
ya
thats what i mean they are still updated but not used any more
Oh @phillipskevin do you maybe know or tryed it what happens to a 2.3 project when you switch do can3.0
and use the legacy stuff does it work?
ya upgrading means for me also changing the components
i mean it works to only change the requires and imports and they still work nothing left out?
there’s a migration guide: http://v3.canjs.com/doc/migrate-3.html#Minimalmigrationpath
@roemhildtg to answer your question… I’m not sure
Okay just thought I'd ask. I do know that in the previous version set would be called when the default value was set. http://jsbin.com/wicuguwisa/edit?html,js,console,output
there are some differences with the order of how the define properties get set up
if that’s something you need, feel free to open an issue
canMap.extend(
/ @prototype */
{
define: {
/
* @property {office/models/session} office/components/navigation.loginSession loginSession
* @parent office/components/navigation.properties
*
* A placeholder session with a nested [office/models/user user] property that
* is used for two-way binding the login form's username and password.
*/
loginSession: {
value: function(){
return new Session({user: new User()});
}
}
/**
* @property {office/app} office/components/navigation.app app
* @parent office/components/navigation.properties
*
* The [office/app] used to add or destroy the session.
*/
/**
* @property {Promise<office/models/session>} office/components/navigation.sessionPromise sessionPromise
* @parent office/components/navigation.properties
*
* The promise that resolves when the user is logged in.
*/
},
/**
* @function createSession
*
* Creates the session on the server and when successful updates [office/components/navigation.app]
* with the session. Sets [office/components/navigation.sessionPromise].
* @param {Event} [ev] Optional DOM event that will be prevented if passed.
*/
createSession: function(ev){
if(ev) {
ev.preventDefault();
}
var self = this;
var sessionPromise = this.attr("loginSession").save().then(function(session){
self.attr("loginSession", new Session({user: new User()}));
self.attr("app").attr("session", session);
});
this.attr("sessionPromise", sessionPromise);
},```
you see we have a map and then define:{}
