Hi,
I am using tabs in my page.
When switching between the tabs I get this exception frequently (and not
every time).
java.lang.IllegalStateException: No Page found for component
[MarkupContainer [Component id = link]]
at org.apache.wicket.Component.getPage(Component.java:1819)
at
org.apache.wicket.ajax.AbstractDefaultAjaxBehavior.onRequest(AbstractDefaultAjaxBehavior.java:284)
...
Previously I faced the problem of difference of client-side state and
server-side state with chrome and got a fix implementing the solution at
this link:
http://www.richardnichols.net/2010/03/apache-wicket-force-page-reload-to-fix-ajax-back/
But now I see the simple switching between the tabs in IE8 gives me the
problem.
OS used: Windows7
Browser: IE8
Seeking help.
Thanks in advance,
Tejash
that's most probably a problem with the component hierarchy.
If you call getPage() on a component that is (not yet or not anymore)
added to another component this exception happens.
A possible Condition can be:
someSubmitMethod(ajaxtarget target){
if(someLogicDecides())
{
this.addOrReplace(new OtherPanel())
target.addComponent(getPage()); //<= this getPage() cannot succeed
}
}
this may be not your case but there are many similar conditions with
replace mechanism where this may happen. Look for replace mechanism and
check them.
