Re: CouldNotLockPageException in production
Martin, thank you, I could resolve this problem yesterday, I share the
solution because it helps somebody
We have a backend, and in some custom searches it can take 50 or 60 seconds
(or more) to get the results.
When the backend is searching, and the user press BACK BUTTON, we've a
strategy that tries to get the SAME page (same instance) and in this point
is where the exception raises. This is is because we don't use page
versioning, so the home page has always the page-id 1. So:
* when the page is blocked searching, and more than 1 minute has happened
(default time), if the user press BACK BUTTON and wicket tries to recover
the same page-instance, the exception CouldNotLockPageException is rised
* if we have the same scenario but the user press BACK BUTTON before 1
minute, nothing happens (works fine)
So we've done 2 solutions
First, change the default request timeout to 5 minutes, doing this:
Application#getRequestCycleSettings().setTimeout( Duration.minutes(5) );
(because we know that our backend can take all that time)
Then, in my exception-handler, if CouldNotLockPageException is rised, I
capture it, and then I invalidate the session and I force redirection to
login page.
If someone needs the code of the exception handler (method onExcetion() )
(..)
boolean couldNotLock = anException.getCause() != null
anException.getCause().getClass().equals(InvocationTargetException.class)
anException.getCause().getCause() != null
anException.getCause().getCause().getClass().equals(CouldNotLockPageException.class);
if (couldNotLock) {
- invalidate session
- redirect to login page
}
(...)
thanks

Re: Relative Path and Resource loading in wicket
I had a similar problem and considered Martin's approach, but ended up
creating a div wicket:id=myVar class=myVarvar value/div on my
page and accessed it from JS file using $(div.myVar).text() or
something like that.
The advantage of div approach is that you can test it statically
without deploying the webapp and your JS file can be safely cached by
the browser improving load time.

Re: retriving the actual page instance
Thanks to both. Alec approach worked for me in other case, not in this one. In this case, we had the problem that StaleException was rising, when user open multiple tabs with the same session (like Firefox) In that case, I was invalidating the whole session and redirecting to login. But now, the user stays in the same page (with the last state) using Session.get().getPageManager().getPage( id ) So now, the user can have multiple tabs and works fine.
