Page Is Not Found In Page Map After Some Time.
Hi,
we ofen get this error after performing back several times in an application.
It happens occassionally, does wicket's page map store have a
limitation on the number of times you can store the page?
here's the code in our back button.
we store the page id and version and use that to track the pages.
after a lot of backs in an application, the page disappears from the
page map causing a nullpointerexception.
Is there anything that I could do to prevent this? what is the limit
on the number of pages that a pagemap could store?
@Override
public void onClick() {
if(clazz != null) {
setResponsePage(clazz);
}else if(pageIDVersion != null && webPage == null) {
setResponsePage(getPage().getPageMap().get(pageIDVersion.getId(),
pageIDVersion.getVersion())); //SXIBackButton.java:67
} else if(webPage != null && pageIDVersion == null) {
setResponsePage(webPage);
}
}

Not a complete reply but I think the default limit is 99 versions. This
can be configured.

Re: Page Is Not Found In Page Map After Some Time.
Posted by Horacio Natyural <ho...@gmail.com>.
yep,
its because of this
setResponsePage(getPage().getPageMap().get(pageIDVersion.getId(),
pageIDVersion.getVersion()));
getPage().getPageMap().get(pageIDVersion.getId(),
pageIDVersion.getVersion()) -- this returns a null page after some time.
