How to show some validation error to User using behaviors plugin

Question

This is what I have written in validation script of Behaviors Plugin of jira

FormField  srcd = getFieldByName("SIS Tech Review Completion Date")
FormField  srsd = getFieldByName("SIS Tech Review Start Date")
String compdate = srcd.getValue()
String startDate = srsd.getValue()
if (compdate < startDate){
    srcd.setError("error") 
}

Once I put "compdate < startDate" in JIRA field of the ticket , suddenly JIRA field becomes non-editable. I am not sure how can I inform User about this validation with message :

"SIS Tech Review Completion Date should be greater than SIS Tech Review Start Date"

It looks ok to me, but you need to clear the error once that condition is not true. It doesn't happen by magic.

So you need an else block with srcd.clearError() or whatever, can't remember syntax right now.

If that doesn't help can you add some screenshots.

Is there any reason you aren't using a workflow validator to accomplish this?
