Required field validation for Legacy people picker control

[shanthisri]

Hi All,

   I'm trying to make a Legacy control people control as a mandatory field and couldn't find a correct way to do that using Nintex rules or Javascript. Can anyone please help me with a solution if there's any. 

Note: I have tried to use People control under General and rules are working perfectly for that control but the issue is it is taking too long to resolve the username which makes me to go for Legacy people picker control.

Hi,
I was in the same situation a while ago. I had to find a solution quickly, so here is what I did :

1. I added a calculated field that get information from the people picker control.
2. I added a rule to this calculated field to make him mandatory (not null or empty).
3. I have created a custom message to inform the user that this field is mandatory.

Hopefully this will help.

I have found an another solution, created that list column as mandatory so by default the legacy control had that validation applied.
