After integrating with YII Framework cant add new events

<?xml version='1.0' ?><data><action type='invalid' sid='1395207951278' tid='1395207951278' details='Rec Type cannot be blank. Event Pid cannot be blank. Event Length cannot be blank.' ></action></data>

this is the response i am getting

It seems that you have some validation rules assigned to the related model class, and those validation rules is not in sync with data provided by the scheduler.

solved thanks
