Zsolt Süli commented on WICKET-948:
-----------------------------------
There's no form in these pages.
I have a page (say HomePage ... like this:
public class HomePage extends WebPage {
private static final long serialVersionUID = 2429832495146545152L;
public HomePage() {
super();
add(new Link("link")
{
public void onClick()
{
setResponsePage(StatefulPage.class);
}
});
}
}
It calls StatefullPage, which is a statefull page (for example it has a
PageLink component ... nothing more). When I see StatefullPage, and push a back
button, HomePage shown, but when I click on the link, it threw this exception.
Everything is OK, if
- I make my HomePage stateless (say replace Link with StatelessLink)
OR
- I make my StatefullPage stateless (by using BookmarkablePageLink instead of
PageLink)
This is where it takes:
/**
* De-serializes an object from a byte array.
*
* @param data
* The serialized object
* @return The object
*/
public static Object byteArrayToObject(final byte[] data)
{
try
{
final ByteArrayInputStream in = new
ByteArrayInputStream(data);
try
{
return
objectStreamFactory.newObjectInputStream(in).readObject();
}
finally
{
in.close();
}
}
catch (ClassNotFoundException e)
{
throw new RuntimeException("Could not deserialize
object using `"
+
objectStreamFactory.getClass().getName() + "` object factory", e);
}
catch (IOException e)
{
throw new RuntimeException("Could not deserialize
object using `"
+
objectStreamFactory.getClass().getName() + "` object factory", e);
}
}
--- so this line is the source of the problem :
return objectStreamFactory.newObjectInputStream(in).readObject();
--- thx for the reply
