Hi All,
I have following tag in my JSf page.
<h ataTable id="teamInfoTable" value="#{pc_AdminMenu.teamMembers}" var="member">.............
Here value is assigned to backing bean's property which is of Collection type. This collection contains objects of UserInfo bean . Now can anybody tell me how does tag processing happens? I mean how the evaluator come to know class type of objects in the Collection . Because when we call get methos on the collection object it returns it as Object but to use it as UserInfo bean object we have to type cast it into UserInfo class instance. And if i am not wrong java doesn't support runtime type casting . I really wonder how JSF creator acheived this . Plz guide me thru this.
Thanks in advance.
