Table sort Exception

Hello, we are trying to use soft-references addon. In our problem there are 3 entittes:

 @Table(name = "FIRST")
 @Entity(name = "test_First")
 @NamePattern("%s %s|requestNum,requestDate")
 class First extends StandardEntity {
       @Column(name = "REQUEST_NUM", nullable = false, unique = true)
       @NotNull
       private Long requestNum;
   
      @Temporal(TemporalType.DATE)
      @NotNull
      @Column(name = "REQUEST_DATE", nullable = false)
      private Date requestDate;
   
      // getter and setter
 }


 @Table(name = "SECOND")
 @Entity(name = "test_Second ")
 @NamePattern("%s|name")
 class Second extends StandardEntity {
    @NotNull
    @Column(name = "NAME", nullable = false, length = 512)
    protected String name;
   
    // getter and setter
 }

And 3d entity witch refersTo first and second entity

@NotNull
@MetaProperty(datatype = "EntitySoftReference")
@Column(name = "REFERS_TO", nullable = false)
@Convert(converter = EntitySoftReferenceConverter.class)
protected com.haulmont.cuba.core.entity.Entity refersTo;

When we have a table with 3d entity and one of columns is refersTo. if we try to sort table by refersTo there will be:

java.lang.IllegalArgumentException: Can't find getter for property 'requestNum' at class com.test.entity.Second

And sometimes same Exception but: java.lang.IllegalArgumentException: Can't find getter for property 'name' at class com.test.entity.First

Is it possible to fix it somehow?

Hi,
Built-in CUBA Table behavior is to apply column sorting to the JPQL query used in the collection container - add “order by columnName” clause to the query string.
With soft-reference table column - sorting by the database column isn’t possible.

Possible solutions:

  1. Set sortable = false to this column.
  2. Implement custom collectionContainer sorter. Information is available here: https://doc.cuba-platform.com/manual-7.2/gui_data_comp_sort.html
