Something wrong

[Erwan ROBERT]

Hello,
I'm missing a little something. My need is to add a tab on the software class that contains the expression of software needs by my organizational entities. So I created an extension for that. I started by adding the field to the class:

    <field id="needs_list" xsi:type="AttributeLinkedSet" _delta="define"> 
      <linked_class>Needs</linked_class>
      <ext_key_to_me>software_id</ext_key_to_me>
      <edit_mode>in_place</edit_mode>
      <tracking_level>all</tracking_level>
      <count_min>0</count_min>
      <count_max>0</count_max>
    </field>

And I defined this class like this:

<class id="Besoin" _delta="define">
  <parent>cmdbAbstractObject</parent>
  <properties>
    <category>bizmodel,searchable</category>
    <abstract>true</abstract>
    <key_type>autoincrement</key_type>
    <db_table>besoin</db_table>
    <db_key_field>id</db_key_field>
    <db_final_class_field>finalclass</db_final_class_field>
    <naming>
      <attributes>
        <attribute id="software_id"/>
      </attributes>
    </naming>
    <display_template/>
    <icon>images/besoin.png</icon>
    <reconciliation>
      <attributes>
        <attribute id="software_id"/>
        <attribute id="software_name"/>
      </attributes>
    </reconciliation>
  </properties>
  <fields>
    <field id="software_id" xsi:type="AttributeExternalKey">
      <sql>software_id</sql>
      <target_class>Software</target_class>
      <is_null_allowed>false</is_null_allowed>
      <on_target_delete>DEL_AUTO</on_target_delete>
    </field>
    <field id="software_name" xsi:type="AttributeExternalField">
      <extkey_attcode>software_id</extkey_attcode>
      <target_attcode>name</target_attcode>
    </field>
    <field id="org_id" xsi:type="AttributeExternalKey">
      <sql>org_id</sql>
      <target_class>Organization</target_class>
      <is_null_allowed>false</is_null_allowed>
      <on_target_delete>DEL_MANUAL</on_target_delete>
    </field>
    <field id="org_name" xsi:type="AttributeExternalField">
      <extkey_attcode>org_id</extkey_attcode>
      <target_attcode>name</target_attcode>
    </field>
    <field id="nombre_besoin" xsi:type="AttributeInteger" _delta="define">
      <sql>nombre_besoin</sql>
      <default_value/>
      <is_null_allowed>true</is_null_allowed>
    </field>
    <field id="status" xsi:type="AttributeEnum">

        <value id="draft">draft</value>
        <value id="published">published</value>
        <value id="obsolete">obsolete</value>
      </values>
      <sql>status</sql>
      <default_value/>
      <is_null_allowed>true</is_null_allowed>
      <display_style>list</display_style>
    </field>
  </fields>
  <methods/>
  <presentation>
    <details>
      <items>
        <item id="software_id">
          <rank>10</rank>
        </item>          
        <item id="org_id">
          <rank>10</rank>
        </item>
        <item id="nombre_besoin">
          <rank>20</rank>
        </item>           
        <item id="status">
          <rank>50</rank>
        </item>
      </items>
    </details>
    <search>
      <items>  
        <item id="org_id">
          <rank>20</rank>
        </item>
        <item id="status">
          <rank>30</rank>
        </item>
      </items>
    </search>
    <list>
      <items>
        <item id="org_id">
          <rank>10</rank>
        </item>
        <item id="status">
          <rank>20</rank>
        </item>
        <item id="nombre_besoin">
          <rank>30</rank>
        </item>
      </items>
    </list>
  </presentation>
</class>

The tab appears correctly in the display (excluding the dictionary), but when I use the create button. Instead of displaying the window correctly, I get a piece of nothing. And I don't understand where my error is.

This is bad, you cannot create an abstract class object
<abstract>true</abstract>
