I have some validation rules in schema which automatically get triggered when we try to create/update but some user able to bypass that by using “Change of Status”. Is there way to trigger validation during Change of Status (i.e. from Draft to Published)?
No, the validation usually only trigger when the content is changed.
But I do not understand how they are able to bypass the validation.
Yes, I understand that, but it also does not change the content, so it does not bypass validation.
I wanted to make sure some fields gets populated before content gets published. Is there a way I can trigger validation when this change occurs? Some kind of Post script ?
No, it is not possible. You can convert this topic to a feature request if you want.
Thanks, I will submit this as New Feature Request.
