Hi, I have asked this question on asp.net forums (http://forums.asp.net/t/1545006.aspx) but i had no valid answer therefore i'll try this here as well.

I was working on migrating MVC1 app to MVC2 today and i have come across a problem while changing the ValidationMessage to ValidationMessageFor implementation.

The below is the selectlist in my View

<%=Html.DropDownListFor(model => model.SecurityQuestions[0].Question,  "Some Security question", new { @class = "form_element_select" })%>

The below code works fine and i can see the validation message came from modelstate.

<%= Html.ValidationMessage("SecurityQuestions_0__Question")%> 

but this one does not work:

<%= Html.ValidationMessageFor(model => model.SecurityQuestions[0].Question)%>

SecurityQuestions is a generic list in my model

public List<SecurityQuestion> SecurityQuestions { get; set; }

Is this somewhat a bug in "ValidationMessageFor" or am i missing something here?
