I think you misunderstood my question. What I'm talking about is if the validation fails. In controller I don't do any redirect if validation fails. It simply sets errors variable to be passed to add view and the view is rendered with previously entered values along with error messages. This works ok except for dependent select list (id= appilcation) which is displayed without any option. It is because the options in dependent select list is created with jquery when there is a change in another select list (id=document) (I set onChange event to document select list). I can get the value of previously entered value for dependent select list option in controller. So my question is, how can I display options in dependent select list with correctly selected value if validation fails ?
What I'm thinking now is that I set a variable in controller when validation fails. This variable will be passed to jquery.(this creates another problem that I don't quite understand, which is passing variable from controller to javascript/jquery) In jquery, we will check if this variable is set. If it is, then create options for dependent select list and select an option with previously selected value. Otherwise create options with no selection. Or maybe anyone has another ideas ?? Thanks..
