LocalizedImageResource does not serialize locale/style fields
-------------------------------------------------------------
Key: WICKET-1062
URL: https://issues.apache.org/jira/browse/WICKET-1062
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 1.3.0-beta4
Reporter: John Ray
I have a page where clicking an AjaxLink causes an Image to be updated. In the
onClick() method of the link I change the image via
setImageResourceReference(). I then call AjaxRequestTarget.addComponent(image)
to have the image rendered.
Everything works great when the page is first loaded however if I navigate to a
different page and then back again the image doesn't update the first time I
click the link. The problem is that the LocalizedImageResource saves the
current locale/style in transient fields when it is first created. By
navigating to a different page and then back again it causes the class to get
serialized and the locale and style are initialized to null. In
setSrcAttribute() this code then compares the locale against the image
component's locale.
Locale l = component.getLocale();
String s = component.getStyle();
if (resourceKind == null ||
(!Objects.equal(locale, component.getLocale()) || !Objects.equal(style,
component
.getStyle())))
{
// Get new component locale and style
locale = component.getLocale();
style = component.getStyle();
// Invalidate current resource so it will be reloaded/recomputed
resourceReference = null;
resource = null;
}
Since the local in LocalizedImageResource was not serialized it never matches
and my call to setImageResourceReference() is basically ignored.
If you just remove the transient keyword from the locale and style fields it
fixes the problem.
