------------------------------------
Summary: Javascript error when closing a ModalWindow with IE 8
Key: WICKET-4695
URL: https://issues.apache.org/jira/browse/WICKET-4695
Project: Wicket
Issue Type: Bug
Components: wicket-extensions
Affects Versions: 1.5.5
Environment: Internet Explorer 8
Reporter: Juha Syrjälä
Priority: Minor
Closing a ModalWindow in IE 8 may cause following javascript error to console:
'win.current' is null or not an object
This doesn't happen with Chrome or Firefox and software seems to work
correctly: ModalWindow closes correctly etc. This doesn't happen with all
ModalWindows in my application, but if it happens, it will happen every time. I
don't know what triggers this behavior, but a work around is to add null checks
to ModalWindow.java and modal.js, currently there are only check for undefined
variables.
ModalWindow.java, getCloseJavacriptInternal(), line 416 in wicket-1.5.5 source
+ "if (typeof(win) != \"undefined\" && typeof(win.current) != \"undefined\" &&
win.current != null) {\n"
modal.js, Window.close, line 258
if (typeof(win) != "undefined" && typeof(win.current) != "undefined" &&
win.current != null) {
