[OPEN] [#806] Possible BUG in Menu Horizontal with Chrome

[equiman]

I have a problem with Menu Horizontal component, when mouse is over a MenuItem I cant click on it because hide this Menu.
I'm testing with another browsers but only happens with Chrome:

Ext.Net Version 2.5.3 (Pro)
Google Chrome Version 43.0.2357.65 m (FAIL)
Internet Explorer Version 11.0.9600.17801 (OK)
Firefox Version 36.0.1 (OK)
Safari Version 5.1.7 (7534.57.2) (OK)
Opera Version 27.0.1689.76 (OK)

You can test and reproduce it whit this sample

I made a video with this possible bug:

In this video when I use chrome, seem like I'm clicking the options, but not I'm only moving the mouse over the MenuItem options.

Thanks to @price56k I found the solution in ExtJS Forum:

Option 1:

Option 2:

I't will be great if Ext.Net Team make the same correction.

Thanks!

I'm sorry for the silly question, but how I can apply the patch to my Ext.Net project?
In which file I must add this code?

// fix hide submenu (in chrome 43)
Ext.override(Ext.menu.Menu, {
    onMouseLeave: function(e) {
    var me = this;


    // BEGIN FIX
    var visibleSubmenu = false;
    me.items.each(function(item) { 
        if(item.menu && item.menu.isVisible()) { 
            visibleSubmenu = true;
        }
    })
    if(visibleSubmenu) {
        //console.log('apply fix hide submenu');
        return;
    }
    // END FIX


    me.deactivateActiveItem();


    if (me.disabled) {
        return;
    }


    me.fireEvent('mouseleave', me, e);
    }
});

Thanks

Found the place. At first, I thought to modify some file of the Ext.NET library ...

Thanks

Hello!

Thank you for the report and investigation! Created an Issue:
https://github.com/extnet/Ext.NET/issues/806

I am a little bit reluctant to apply those fixes, because I am not sure it doesn't break something else.

So, for know we are just keeping an eye on that.

Also there is probably a chance that it might be resolved with a next Chrome release.

[neaplus]

the bug only occurs current version of Chrome v43, v42 and new beta v44 is ok.
