Hi all,
I'm doing a drag-proxy like this:
---
this.element = element;
this._proxy = this.element.cloneNode(true);
this._proxy.absolutize();
this._proxy.style.opacity = 0.7;
this._proxy.clonePosition(element);
this._proxy.observe('mouseup', this.destroy.bind(this));
this.element.observe('mouseup', this.destroy.bind(this));
document.body.appendChild(this._proxy);
new Draggable(this._proxy).initDrag(ev);
---
which is necessary so that the draggable is rendered as a child of
document.body and therefore can float over scrollable divs.
However, now the proxy captures mouseup events, which nullifies the
original element's click and doubleclick events (probably not the best
idea to have mousdown, up, click, and doubleclick all on one element,
but oh well). So I want to route event bubbling from the proxy to the
parent, but keep the proxy a child of document.body. I think I only
really need to route mouseup. So I tried this:
---
this._proxy.observe('mouseup', function(ev)
{this.element.dispatchEvent(ev);}.bind(this));
---
but that throws this error, which is rather incomprehensible:
---
[Exception... "Component returned failure code: 0x80070057
(NS_ERROR_ILLEGAL_VALUE) [nsIDOMEventTarget.dispatchEvent]" nsresult:
"0x80070057 (NS_ERROR_ILLEGAL_VALUE)" location: "JS frame ::
http://localhost:3000/javascripts/behaviors.js?1211228591 ::
anonymous :: line 12" data: no]
---
Can anyone please shed some light on how to approach this problem?
Thanks,
Ian
