[OpenLayers-Users] OpenLayers.Feature.Vector hover + click event

[_greg_]

I think the "problem" is in this method inside OpenLayers.Handler.Feature:

triggerCallback: function(type, mode, args) {
        var key = this.EVENTMAP[type][mode];
        if(key) {
            if(type == 'click' && this.up && this.down) {
                // for click/clickout, only trigger callback if tolerance is
met
                var dpx = Math.sqrt(
                    Math.pow(this.up.x - this.down.x, 2) +
                    Math.pow(this.up.y - this.down.y, 2)
                );
                if(dpx <= this.clickTolerance) {
                    this.callback(key, args);
                }
            } else {
                this.callback(key, args);
            }
        }
    }


First time click on draggable feature I have this.down = null, so bottom
this.callback gets executed.
At second click this.down is not null - dpx is calculated and it is always
larger than this.clickTolerance (default value = 4). So, I set it up to some
large value and seems ok - don't know for side effects.
I guess the problem is in this.down value.
