Filtering Issues while using Dependant Select box

Hi Everyone,

I am getting an error while using Dependant Select box feature. It is working fine all except when I am using concat two fields in setRelation function.

for example,

Getting Error below code

$crud->setRelation('exemption_student_id', 'dice_students', '{student_first_name} {student_last_name}', ['student_active' => 0]);

This same will work when I am removing the concat fields and use single field like below.

$crud->setRelation('exemption_student_id', 'dice_students', 'student_first_name}', ['student_active' => 0]);

Can anyone please help me?

Thanks
