Hi,
I created a quickstart but was unable to reproduce the problem.
I traced down the roots of the error and found out that the
LoadableDetachableModel-s that my repeater views use get their object
detached IMMEDIATELY after page gets rendered. And this happens only when
the application is browsed via IE.
Here is a snippet from the logs:
10-09-2011 19:15:56,197 DEBUG org.apache.wicket.Page.componentRendered:395

render [Page class = ui.Canvas, id = 1, version = 0]

As you can see model is detached right after page render and therefore the
model object's data cannot be processed.
Thank you,

Hello,
I have the following problem. I have a repeater which declares Images
as so:
NonCachingImage image1 = new NonCachingImage("image1", new
BufferedDynamicImageResource() {
private static final long serialVersionUID = 1L;
@Override
protected byte[] getImageData() {
return detachable.getObject().getItem1().getThumbData();
}
});
When the repeater is rendered and displayed in IE, getImageData is not
called and therefore images are not shown. However, if I copy the
image src
and hit that URL, the image gets loaded.
I believe for some reason IE thinks the image is cached, although it
has never beed loaded and therefore does not retrieve the source of
the image. Don't know if this is the real reason.
Has anybody been into this issue before?
Regards,
Martin
