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);
   }

Можно и так но мно кода нужно написать !

Query query = new Query();
QueryBuildDataSource queryBuildDataSource;
QueryBuildRange queryBuildRange;

// Create an instance of SysTableLookup where 'this'
// is the current form control.
SysTableLookup sysTableLookup =
SysTableLookup::newParameters(tableNum(custTable), this);
;

// Add fields to be shown in the lookup form.
sysTableLookup.addLookupField(fieldNum(CustTable, AccountNum));
sysTableLookup.addLookupField(fieldNum(CustTable, Name));

// Limit and arrange the data selection.
queryBuildDataSource = query.addDataSource(tableNum(CustTable));
queryBuildRange = queryBuildDataSource.addRange(
fieldNum(CustTable, AccountNum));
queryBuildRange.value('0..Z');
sysTableLookup.parmQuery(query);

// Perform the lookup.
sysTableLookup.performFormLookup();

//Don't call super() (commented out in the code).
// super()

Сообщение от AndrianG

// Add fields to be shown in the lookup form.
sysTableLookup.addLookupField(fieldNum(CustTable, AccountNum));
sysTableLookup.addLookupField(fieldNum(CustTable, Name));

Ну... просто прочитайте хелп дальше.
достаточно просто унаследовать тип контрола от CustAccount.
Тогда вообще ничего писать не придется.

Если же так хочется пописать (с любым ударением в слове),
то для такого простого лукапа наверняка лучше просто юзать performTypeLookup(typeId(CustAccount)).
