[jira] [Created] (WOOKIE-359) Widget.preferences.setItem don´t work if widget contains an iframe with a remote src
Michael Hertel created WOOKIE-359:
-------------------------------------
Summary: Widget.preferences.setItem don´t work if widget contains an iframe with a remote src
Key: WOOKIE-359
URL: https://issues.apache.org/jira/browse/WOOKIE-359
Project: Wookie
Issue Type: Bug
Components: Server
Affects Versions: 0.11.0
Environment: Win7 x86
Reporter: Michael Hertel
Priority: Minor
Bug occurs by using an iframe with a remote url inside the widget. In that case the user agent always denies the access to the property 'dispatchEvent' (wookie-wrapper.js, line 229), if the "widget.preferences.setItem" function is called. Seems to be a cross-origin request issue.

[jira] [Commented] (WOOKIE-359) Widget.preferences.setItem don´t work if widget contains an iframe with a remote src

Scott Wilson commented on WOOKIE-359:
-------------------------------------
Thanks for the bug report Michael.
The problem lies wookie-wrapper.js, with this function:
this.__raiseEvent = function(key, value, oldValue){
//
// Raise custom storage event
//
var evt;
if(document.createEvent){
evt = document.createEvent("Event");
} else { // IE before v 9
evt = document.createEventObject(window.event);
}
var evt = document.createEvent("Event");
evt.initEvent("storage", false,false);
evt.key = key;
evt.newValue = value;
evt.oldValue = oldValue;
evt.url = window.location;
evt.storageArea = widget.preferences;
//
// Dispatch to child frames
//
var frames = window.frames;
for (var i=0;i<frames.length;i++){
if(document.createEvent){
frames[i].dispatchEvent(evt);
} else { // IE before v 9
frames[i].fireEvent("storage", evt);
}
}
}
One solution is to only fire events at same-origin frames; another is to handle exceptions rather than let them reach the user.
