How to show errors for multiple object forms - Play Framework 2 with Java -


i’m having trouble displaying errors of form containing multiple objects of class, in case productmilestone. i’m showing form milestones in table, displaying , updating works well. error template can’t displayed anymore error "[illegalstateexception: no value]". because erroneous form doesn’t contain values received form.get() method, in case it’s milestoneset. can make work errors displayed?

the problem for-loop in view:

view: 

@(milestoneformset: form[productmilestone.milestoneset], productreleaseid: long)     @*function called loop in form below*@     @milestonefields(milestone: productmilestone, index: integer) = {         //…other fields         @inputtext(milestoneformset("milestonelist[" + index + "].initialdate"),  '_label -> "",'class -> "datepicker")       …}  @form(routes.productmilestones.submitedit(productreleaseid), 'id -> "submitmilestoneeditform") {         @*here problem, when form has error can not access milestonelist using in loop*@     @for((milestone, index) <- milestoneformset.get.milestonelist.zipwithindex) {         @milestonefields(milestone, index)         }  }

controller:

public static result submitedit(long productreleaseid) {   form<milestoneset> filledform = form(milestoneset.class).bindfromrequest();   if (filledform.haserrors()) {            return badrequest(views.html.milestonesedit.render(filledform,     productreleaseid));   } else {     milestoneset newmilestoneset = filledform.get();     //...update code }

the method trigger validation can't use in view, can pass set view variable.
