"Dependecies" tab doesn't show any information for a selected table version 4.0

Question

Hello,
I work with SQL Developer 4.0.0.13. I can see 20 tables in the list. When I select one table, in the tabs on the right side I can see information for "columns" and "data" and "constraints" and "indexes"... but the tab "Dependencies" doesn't show any information about references between this table and other tables in the schema.
Oracle database is v11.2
Can you please tell me what do I need to do in order to see information on "Dependencies" tab for a table?
Thank you,
Milan

Hi, here is my example of XML extension showing referencing tables:
Save the following XML to a file.
<items>
  <item type="editor" objectType="TABLE">
    <title><![CDATA[*Referencing Tables]]></title>
      <query>
        <sql><![CDATA[SELECT
  cfk.owner "OWNER",
  cfk.table_name "TABLE NAME",
  cols.column_name "COLUMN",
  cfk.constraint_name "CONSTRAINT NAME",
  cfk.delete_rule "DELETE RULE",
  'SQLDEV:LINK:' || cfk.owner || ':TABLE:' || cfk.table_name ||
  ':oracle.dbtools.raptor.controls.grid.DefaultDrillLink' "LINK"
FROM
  sys.all_constraints cpk,
  sys.all_constraints cfk,
  sys.all_cons_columns cols
WHERE
  cpk.owner = :OBJECT_OWNER AND
  cpk.table_name = :OBJECT_NAME AND
  SUBSTR(cpk.table_name, 1, 4) != 'BIN$' AND
  SUBSTR(cpk.table_name, 1, 3) != 'DR$' AND
  cpk.constraint_type in ('P', 'U') AND
  cfk.r_owner = cpk.owner AND
  cfk.r_constraint_name = cpk.constraint_name AND
  cfk.constraint_type = 'R' AND
  cols.owner = cfk.owner AND
  cols.constraint_name = cfk.constraint_name
ORDER BY
  cfk.owner, cfk.table_name, cfk.constraint_name,
  cols.column_name]]>
      </sql>
    </query>
  </item>
</items>
In SQLDeveloper select Preferences -> Database -> User Defined Extensions and click <Add Row>.
In the "Type" field enter "EDITOR" and in the "Location" field enter the path to the file with XML.
After restarting SQLDeveloper You should see a new tab "*Referencing Tables" for tables.
