Подскажите в чем проблема у Lookup

[AndrianG]

Хочу перекрыть метод lookup и при нажатия на стелку чтобы появилась таблица СustTable , делаю все как показано ниже и при нажатии Axapta вырубается !

1. In the AOT, click Forms, and then locate a form that you want to add a lookup form to.
2. Click the form, and then click Designs > Design.
3. Add one of the following types of controls that support a lookup form:
4. DateEdit

• GuidEdit
• Int64Edit
• IntEdit
• RealEdit
• StringEdit
• TimeEdit

1. For more information about form controls, see Create Form Controls.
2. Right-click the control, click Properties, and confirm that the LookupButton property is set to Auto.
3. Click the control, right-click Methods, click Override Method, and then click Lookup.
   The code editor appears.
4. Call the performDBLookup or performTypeLookup member method of one of the following classes:
   FormDateControl
   FormGuidControl
   FormInt64Control
   FormIntControl
   FormRealControl
   FormStringControl
   FormTimeControl
   In the following example, a field ID and a table ID are passed to the performDBLookup method to display the table field when a user clicks the lookup button.
   public void lookup()
   {
   FormStringControl formStringControl;
   ;
   formStringControl = element.design().controlname("myControl2");
   formStringControl.performDBLookup(4,77);
   }
