class function gets an error

[erickyim]

I add a class function hello() to demo.js:

defineClass('JPTableViewController : UITableViewController', {
    ...
    tableView_heightForRowAtIndexPath: function(tableView, indexPath) {
        return 60
    }
}, {
    //class method definitions
    hello: function() {
        console.log("hello");
        return "I'm JPTableViewController"
    }
})

And called hello():

defineClass('JPViewController', {
    handleBtn: function(sender) {
        var tableViewCtrl = JPTableViewController.alloc().init();
        console.log(JPTableViewController.hello());

        self.navigationController().pushViewController_animated(
            tableViewCtrl, YES)
    }
})

hello() works, (it prints logs,) but rises an error:

2015-05-26 19:29:46.642 JSPatchDemo[31797:867980] JSPatch.log: hello

I notice in #10 you said "By now, JSPatch can't add method to an OC class if the method not exists in OC". Thanks for your work~

@cyvoit That's an other bug, also fixed in 653074f

Great! I still use example above.
And called hello():

defineClass('JPViewController', {
    handleBtn: function(sender) {
        var tableViewCtrl = JPTableViewController.alloc().init();

        self.navigationController().pushViewController_animated(
            tableViewCtrl, YES)
        console.log("self is " + self.description());
        console.log(JPTableViewController.hello());
        console.log("self is " + self.description());
    }
})

It works and no errors.

But called hello() like this:

defineClass('JPViewController', {
    handleBtn: function(sender) {
        var tableViewCtrl = JPTableViewController.alloc().init();
        console.log(JPTableViewController.hello());
        console.log("self is " + self.description());
        self.navigationController().pushViewController_animated(
            tableViewCtrl, YES)
    }
})

It logs:

2015-05-28 10:15:50.969 JSPatchDemo[10737:267688] JSPatch.log: hello
2015-05-28 10:15:50.970 JSPatchDemo[10737:267688] JSPatch.log: I'm JPTableViewController
