Folks,
I am wondering if null properties are suppose to be dealt with morwe gracefully
within T-5.4 as everytime I create an object it works fine and is displayed
within my gallery widget but if I omit property fields declared inside
@Embeddable classes, they get stored in hibernate as nulls and any subsequent
Edits crash the app due to these omissions. Is tapestry suppose to handle this
properly to avoid crash ?
Alleged as follows...
I have a curious EditBlock DisplayBlock issue with regard to entity in
hibernate database.
Here is the model layout
I have Person.Java where Person is a base class Player class
But Person.Java has a data member
private Demographics demographics = new Demographics();
and here is how Demographics is declared
Demographics.Java...
@Embeddable
public class Demographics
ok so
Player extends from Person
Person has demographics
Player declares the following:
@Column(columnDefinition = "longtext", length = 6291456)
@PropertyDescriptor(readOnly = false)
public String getBio() {
return bio;
}
My issue is weird... Currently I can create Players at this demo site
http://psinh.ddns.net:9011/psi/home
If I create a player it gets saved fine
On subsequent EDIT operations (you can edit as player by clicking on any image
in Gallery)...
Only Players who's demographics were all filled in with legitimate string data
get displayed and edited.
The problem being... the app crashes on Players who's Demographics were omitted
on creation and all properties within the @Embedded instance are null.
Its reproducible everytime at http://psinh.ddns.net:9011/psi/home
Here is the crash trace
