lastIndexOf is not a function

[jan.c]

Hi,

Im currently trying out SmartGWT (version: v8.3) for a future project and experiencing an error while trying to display a smartgwt tree with jpa integration.
It works fine until i try to extend the second node within the tree. Then i get the following error:

15:14:27.575:MUP2:WARN:Log:TypeError: _1.lastIndexOf is not a function

The Code for the tree creation is derived from the examples and works fine so far.
My Beandefinition is as follows:

@Entity
@Table (name="Nodes")
public class MyTreeNode{
	
	@Id
	@Column (nullable = false)
	@GeneratedValue (strategy = GenerationType.IDENTITY)
	private Long id;

	@Column (nullable = false)
	private String name;

	@ManyToOne
	@JoinColumn(name="parentId", referencedColumnName="id")
	private MyTreeNode parent = null;


	@Column (nullable = false)
	private int nodeType;
	
	@OneToOne  
    @JoinColumn(name="toolId", referencedColumnName="id")
    private Tool tool;
	
	// Getters and Setters

}

@Entity
@Table (name="Tool")
public class Tool{
	
    @Id
    @Column (nullable = false)
    @GeneratedValue (strategy = GenerationType.IDENTITY)
    private Long id;
    

    @Column (nullable = false)
    private int position;

	//Getters and Setters

}

Be sure to test with the latest patched build (see smartclient.com/builds). If you already are, be sure to post your full version (not just 8.3).
