Related to required in activity popup in calendar view


I need that the field related to present in Meetings, Calls and Task will be required to save the record in those forms. I already did that by changing the code in …/custom/modules//metadata/editviewdefs.php, just adding:

‘displayParams’ =>
array (
‘required’ => true,

in the properties of the field. My problem is when the user create the meeting or call using the popup in the calendar view. In that case, the field related to appear not required.

I just need to know where and how can I change the properties of the field in that view.
