Hello,
I have the following KeyMap in an mvc view which is referencing a window, where "HomeWindow" is the ID of the window...

                    Html.X().KeyMap()
                        .Target ( "HomeWindow")
                        .Binding
                            ( b => b.Add
                                ( Html.X().KeyBinding ( )
                                    .Handler ( "this.close()" )
                                    .KeysString ( "enter" )
                                )
                            );
it worked in version 4.2.1, but in version 4.5.1 it is throwing the following error...

Unable to get property 'isComponent' of undefined or null reference

Source = http://localhost:3000/Clearview/Sunr...xt.axd?v=4.5.1 at LineNo 20 at Position 1069792
When i go to that line in the ext code, it is as follows...

if(!a.target.isComponent){a.target=Ext.get(a.target)}
Is it expecting a different type of target than the one i have provided? I also tried setting the target to...

Ext.getCmp("HomeWindow")
but got the same error.
