[ solved ] - Service Contracts - doubt

[rslemer]

First is a module I want changed, right?
But in array, references another two modules ...

For example, I wish add a cbCalendar in ServicesContracts how I change that?

$module = Vtiger_Module::getInstance("HelpDesk");
$field = Vtiger_Field::getInstance('parent_id',$module);
$field->setRelatedModules(array('Accounts','Contacts'));
