HI,
I have created a job, which is 'build parameterized'. Each params are of type 'Validating String Parameter'.

1. When i trigger this job manually (say Click on Job -> Build With Parameters), URL goes like this "http://server:8080/view/view_name/job/job_name/build?delay=0sec" , Field validation for params is applied during this trigger.
2. When i trigger this job via parambuild URL "http://server:8080view/view_name/job/job_name/parambuild/?param1=10.10.10.10", Field validation missing during this trigger
