The problem is in labelProperty. If I removed that attribute, it works (at least, it display desired page). The problem is combo box labels are not defined correctly. I've checked psychotestInstituteLabels, and it contains correct values. Even if I write tag "property = "psychotestInstituteLabels"", it displays correct value. But when I'm using labelProperty, it becaomes messy. What happened? In other pages that uses html:select, all labelProperty tag works just fine, only in this page it becomes bad.
