Upgrade to wicket 6 giving blank page in IE 9
Hi,
Am currently upgrading my project to wicket 6.9
Am facing a sporadic issue where sometimes page comes up blank (Only the
image placed at top of page comes fine). This error comes on any random
screen (not specific to a certain screen).
I tried to narrow down the scenario when this error occurs:
- This error occurs in IE 9, does *not* occur in Firefox 10
- This error occurs with RenderStrategy as REDIRECT_TO_BUFFER and
REDIRECT_TO_RENDER, but does *not*occur with RenderStrategy as
ONE_PASS_RENDER
- After the blank page comes up, if I hit the Refresh or Back button, the
same page comes up fine
Changing the RenderStrategy is not an option currently.
It appears IE is causing the connection to close sporadically. Not quite
sure what is going on.
Any help will be much appreciated.
Thanks,
Prasad

I think this is something browser related, IE while deciding which rendering technique to adopt can do strange queries. It could be interesting if you dumped what happens on network using IE or another "working" browser with your old non working code.

Not exactly sure how Wicket uses the DOCTYPE while rendering and the

This has nothing to do with Wicket, is just that IE likes to be different and
mess things up almost always :)
Read about the Defining document compatibility on MSDN:
http://msdn.microsoft.com/en-us/library/cc288325(v=vs.85).aspx
And then pay attention to the links at the bottom of the article:
* When to use legacy document modes
* Controlling default rendering

Let me guess, the image that always shows up is a static resource w/o any
wicket id?
I remember I had a similar problem and if you look inside your webapp server
logs you would see the errors/warnings from Wicket.
If I remember right I fixed it by sticking to strict HTML 4.01.
Try adding the following to all of your pages:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
See if that does the magic for you.

Hi, what is the server environment you're facing this issue with? Did you
change something else than Wicket version ? From which one are you coming
from ?
Thanks for the answers !
