Hide printable document button for worker and participants

Content

Hi,

I'm customizing the printable document button to hide it for the roles of workers and participants

The expression I used is #{pageFlowScope.pRoleTypeCode == 'MANAGER'} when I try it it indicates false when I do the test

But with #{pageFlowScope.pRoleTypeCode == NULL} , it indicates true

I do the test and logging the system as line manager does not show me the print button.

Any similar case?

Best Regards,

Mirtha.
