Possible bug in Safari with fireEvent

[dimitar]

Hi,

I noticed that when I call:

var record = #{MyGrid}.getStore().getById(record_id);
record.set('some_data', 'test');

In Safari this code throws an error: 'undefined is not an object'
and after some tracing, the problem was located in
Ext.util.Observable.fireEvent()

fireEvent: function () {
        var a = Array.prototype.slice.call(arguments, 0),
            ename = a[0].toLowerCase(),
            me = this,
            ret = true,
            ce = me.events[ename],
            cc,
            q,
            c;
        if (me.eventsSuspended === true) {
            if (q = me.eventQueue) {
                q.push(a);
            }
        }
        else if (typeof ce == 'object') {
            if (ce.bubble) {
                if (ce.fire.apply(ce, a.slice(1)) === false) {
                    return false;
                }

                c = me.getBubbleTarget && me.getBubbleTarget();
                if (c && c.enableBubble) {
                    cc = c.events[ename];
                    if (!cc || typeof cc != 'object' || !cc.bubble) {
                        c.enableBubble(ename);
                    }
                    return c.fireEvent.apply(c, a);
                }
            }
            else {
                a.shift();
                ret = ce.fire.apply(ce, a);
            }
        }
        return ret;
    }

The problem was in this line of code at the end:

ret = ce.fire.apply(ce, a);

I don't now but somehow Safari throws an error, and this is native javascript function, so I suspect it's some internal error in the Safari Javascript engine.
I get this case only with the record.set() function, I didn't found this kind of error in other fireEvent cases. This is tested in the latest Safari for Windows (5.1.7) and for Mac OS X (6.0.2).

By the way I solved the problem with overriding this function, and wrapping the problematic code with try-catch block, but I was wondering if someone else got the same problem, and what kind of solution is used.
