Hi,
The problem seems to be somewhere here:
We create an external link with an serializable object as parameter.
In T3 it looked like this:
IEngineService service =
cycle.getEngine().getService(Tapestry.EXTERNAL_SERVICE);
ILink link = service.getLink(cycle, this, getServiceParameters());
url = link.getURL();
where getServiceParameters() returned an Object[] with {Long, String,
ourSerializableObject}
In T4 I did it that way:
@InjectObject("engine-service:external")
public abstract IEngineService getExternalService();
...
ExternalServiceParameter esp = new
ExternalServiceParameter(targetPage, (Object[])
getServiceParameters());
url = getExternalService().getLink(false, esp).getURL();
Now I can see that our serializable object is squeezed as a gzipped
serializable object.
In the URL something like this: "ZH4sIAAAAAAAAAI2SwWoUQRCGa8aMm7gakgh..."
But I still can't explain why the unsqueeze is not able to handle this
gzipped object.
Yes, I know it's not the best way to serialize objects like this. But
for the moment we have no other choise.
Greetings

Could this be a bookmark from the T3 app that you are trying to use under T4?
The stack trace indicates parsing a query parameter that is a gzipped
encoding of a serialized Java object. That's a red flag right there
(just because you can do it, doesn't mean you should ... Serialization
is a very brittle thing).
