Open XAVA How to Put Default value and Join column of another table

1 .For default value I have tried :

@Required 
@Column(name="semester")
@DefaultValueCalculator(value=StringCalculator.class, properties=@PropertyValue(name="value", value="173"))
private String semester;

Getting error :

Error calculating default value

2 . Another Problem is I want to view column of another table into a table.

Table . - Room [id, name] - RoomAssigned [id , capacity , type ,status ]

In view/UI , I am showing RoomAssigned which has CRUD . 

Now its showing column - 
[id,capacity,type,status]

I want to add another column [name] from "Room" table . Here "Room" id is foreign key.

I want to get a view with view / UI : 

 [id,name,capacity,type,status]

I am new in OpenXava.Thanks in advance.

Solution

  • About the second point, you have to put the reference name in the @View members, use a @ReferenceView in the reference and create a @View in the referenced entity.
