Email Validation failing every time on OPC checkout

[William_firefold]

For some reason, OnePageCheckout is not allowing account registration on the page and is saying Email address is not valid, even when the address is valid.
When I remove this particular validator, everything works fine. Obviously this is not a solution though.

Any idea what could cause this problem?

Your application version? Also could you post commented validator code here?

we are upgrading to 7.0.3 so that is the base for the code. We have modifications, but not to this section.

Code: Select all

    
<tr id="trEmail" runat="server" enableviewstate="false">
<th>
<asp:Label ID="BillToEmailLabel" runat="server" Text="Email:" AssociatedControlID="BillToEmail" EnableViewState="false"></asp:Label></th>
<td>
<asp:TextBox ID="BillToEmail" runat="server" EnableViewState="false" Width="200px" MaxLength="250" ValidationGroup="OPC"></asp:TextBox> 
<asp:RequiredFieldValidator  ID="BillToEmailValidator" runat="server" Text="*"
ErrorMessage="Email is required." Display="Static" ControlToValidate="BillToEmail"
EnableViewState="false" SetFocusOnError="false" ValidationGroup="OPC"></asp:RequiredFieldValidator>

<%-- When this code is removed, the registration completes

<asp:RegularExpressionValidator ID="BillToEmailFormatValidator" runat="server" Text="*"
ErrorMessage="Email address is not valid" Display="static" ControlToValidate="BillToEmail"
EnableViewState="false" SetFocusOnError="false" ValidationGroup="OPC"></asp:RegularExpressionValidator>
--%>
</td>
    </tr>
