Hello,
I'm trying to understand the inner working of tapestry, and more precisely
the way the "t:formdata" hidden field is used. For this, i'm trying to
unserialize and instanciate a t:formdata field, saved from a simple form
validation, with the following code :
try {
System.out.println("componentId : " + ois.readUTF());
ComponentAction action = (ComponentAction) ois.readObject();
} catch (ClassNotFoundException e)
{
e.printStackTrace();
}
}
As a result, the ois.readUTF() statement succeeds to complete, as the
println shows, but the readObject (or cast) fails with a
ClassNotFoundException :
componentId : Index:texte
java.lang.ClassNotFoundException:

The packages containing the AbstractField class is include, though :
import org.apache.tapestry5.corelib.base.AbstractField;
import org.apache.tapestry5.ComponentAction;
Would anyone have an idea why the instanciation fails ?
Thanks !
For information, the form template is the following :
