Use callback extension

[Unghy Péter]

Hello,

I tried the Callback action (jb-custom-callback). I made a custom method
in UserRequest:

 <method id="UserRequestAutoAssignOnCreate" _delta="define">
    <static>false</static>
    <access>public</access>
    <type>UserMethod</type>
    <arguments/>
    <code><![CDATA[
      public function UserRequestAutoAssignOnCreate()
      {
          $iSubcategoryId = $this->Get('servicesubcategory_id');
          if (empty($iSubcategoryId)) {
              return;
          }

error_log(">>> func called\n", 3, APPROOT . '/log/autoassign.log');
$oSubcategory = MetaModel::GetObject('ServiceSubcategory',
$iSubcategoryId, false);
if ($oSubcategory == null) {
return;
}
$iSupportTeamId = $oSubcategory->Get('support_team');
if (!empty($iSupportTeamId)) {
$this->Set('team_id', $iSupportTeamId);
}
}
]]>

I have to call it when a userRequest is created.
I used this path : \Ticket\UserRequest:UserRequestAutoAssignOnCreate

I tried to extend the OnInsert method, but it doesn't work:

<method id="OnInsert">
<static>false</static>
<access>protected</access>
<type>Overload-DBObject</type>
<![CDATA
protected function OnInsert()
{
parent::OnInsert();
$this->SetIfNull('last_update', time());
$this->SetIfNull('start_date', time());
$this->UserRequestAutoAssignOnCreate();
error_log(">>> OnInsert called\n", 3, APPROOT . '/log/autoassign.log');
}
]>
</method>

I think the callback is a better solution for me. Could somebody help me?
Thanks in advance
