Required Field Validator Does Not Block Postback

P: n/a
Wow, this is a really embarassing thing to have to ask about...

I have an page with a multiview control in it. We want to enter
person info in a semi - wizard style and I wanted to use required field
validators for, well required fields. On the first view, the person
enters first name, last name and a couple other things. the RFV works
great on first and last name and we move on to the next view -
Addresses. I want to be able to enter multiple addresses so I have an
update button that stores each address entered into a private variable
and clears the form for the next address (yes, it is set to
CauseValidation). The problem is the update button IS NOT causing
client side validation? WTF???

I thought this may be due to the views but I created a quick test
mockup with a MultiView, two views each with a button, a text field and
a RFV. It works every time.
Field and Validator:
<th align="left" nowrap="nowrap">
Address One:
<td width="90%" align="left">
<asp:TextBox ID="txtAddressLineOne" runat="server"
MaxLength="100" Width="250px"></asp:TextBox>&nbsp;
<asp:RequiredFieldValidator id="rfvAddressLineOne"
runat="server" ErrorMessage="Address 1 is a
Required Field" ControlToValidate="txtAddressLineOne"


<asp:Button ID="btnUpdate" runat="server" Text="Update"
OnClick="btnUpdate_Click" CausesValidation="true"/>

Any ideas?
