[FIXED-134][3.0.0] Permission denied to access property 'dom' from non-chrome context

[mschwartz]

also:
e.target.localName == 'HTML'
e.target.tagName == 'HTML'

ps. Does the isXUL method also work for you?

Nope, it fails. However, this works:

Ext.Element.prototype.contains = function(el) {
    if (isXUL(el)) {
        return false;
    };
    return !el ? false : Ext.lib.Dom.isAncestor(this.dom, el.dom ? el.dom : el);

Anyway, I wouldn't restrict it on DataView, as the same problem occurres in Ext.grid.*

here's a completely useless nugget:
Firebug 1.4.0 + Firefox 3.5 now allows logging of the infamous anonymous-div which triggers this error. woot.

I think that's why e.target.localName, e.target.tagName and e.target.children[0].localName actually work, because they would fail in Firefox 2.0 and 3.0.

bingo. attempting to even access any property on that stupidly exposed anonymous-div results in total annihilation.

which then brings us to the next problem -- how do we tackle the problem in Firefox 2+ / <3.5?

does isXUL() still work there if we make the call further up the chain?

[mschwartz]

Try this.

I am not getting the error anymore.

Not tested a whole lot though.

Ext.Element.prototype.contains = function(el) {
    if (el && Ext.isGecko && Object.prototype.toString.call(el) === '[object XULElement]') {
        return false;
    }
    return !el ? false : Ext.lib.Dom.isAncestor(this.dom, el.dom ? el.dom : el); 
};

[ThorstenSuckow]

I'd vote for the isXUL-check, though it introduces some overhead. Depending on the behavior of future FF's, I could also live with the try/catch solution for now.

[mschwartz]

If the above works, awesome.

I like it because you don't have to hack on any of the components like DataView.

[ThorstenSuckow]

Try this.

Ext.Element.prototype.contains = function(el) {
    if (el && Ext.isGecko && Object.prototype.toString.call(el) === '[object XULElement]') {
        return false;
    }
    return !el ? false : Ext.lib.Dom.isAncestor(this.dom, el.dom ? el.dom : el); 
};

This chaining is giving me the creeps ... is that the best we can do to check for a XUL Element?
