try / catch issue

[mmjaeger]

Hello
I'm having some issues with using selector - I've an image element
that gets added to the DOM with some delay - what I came up with so
far is this:

                findImageElement: function(marker) {
                        id = marker.get('id');
                        dbug.log(id);
                        try {
                                el = self.mapCanvas.getElements('img[src$=' + 
id + ']')[0];
                                if (!$chk(el)) throw "error";
                                dbug.log('element found');
                        } catch(e) {
                                this.findImageElement.delay(500, marker);
                        }
                },


the problem I'm having is that recalling the function in the catch
part doesn't pass the marker element again to the function.

I'm kind of lost on this one - is there a better way to do this and if
not, what is the proper way anyway.

Hope somebody can help please.

Thanks
