'ctl00_ctl00_cph1_cph2_ctl00_txtEmail_rfvValue' is null or not an object when a page got loaded

Hi All,

I made a miskate  somewhere in one of the .aspx files that caused an error when a page got loaded:
Here is the error:

From the error message, looks like my page was trying to load a resource, but either the resource is not existed, or its content had been null; further more, that resource might be the textEmail when got verified(rfvValue). I don't know why loading a page will cause a textmail got verified, and even it was null.
Please help.
Thanks a lot.

What page does the error occur on?  Maybe you deleted a required field validator...probably the one on the email field.

After the browser (ie) loaded a apge, there is a status display at the lower left corner. Usually, it says "Done",but when I loaded my Home Page, the display was "Done, but with errors on page.", and a bang (!) in front of it. I clicked the (!), it displayed what I copied here in my initial post.

I notinced, if I loaded other page from there, the lower left corner message is always "! Done, but with errors on Page.", but the content changed slightly. For example, if Home Page is loaded, the display is:

The major differences between loading these two pages are:
loading Home Page displays:

Line: 516
Char: 1
Code: 0
URI: http://www.finepaintinggallery.com/nopcommerce_app/

while loading New Products Page displays:

Line: 983
Char: 1
Code: 0

I looked recentlyaddedproducts.aspx, it has only 7 lines of the code, but at run-time it might loaded other data because it has "cph1" in it.

Thanks for your time.

I found the code in customerinfo.ascx:

                    <td class="item-value">
                        <asp:TextBox ID="txtEmail" runat="server" MaxLength="40"></asp:TextBox>
                        <asp:RequiredFieldValidator ID="rfvEmail" runat="server" ControlToValidate="txtEmail"
                            ErrorMessage="<% $NopResources:Account.E-MailRequired %>" ToolTip="<% $NopResources:Account.E-MailRequired %>"
                            Display="Dynamic" ValidationGroup="CustomerInfo">*</asp:RequiredFieldValidator>
                        <asp:RegularExpressionValidator runat="server" ID="revEmail" Display="Dynamic" ControlToValidate="txtEmail"
                            ErrorMessage="<% $NopResources:Account.InvalidEmail %>" ToolTip="<% $NopResources:Account.InvalidEmail %>"
                            ValidationExpression="[\w\.-]+(\+[\w-]*)?@([\w-]+\.)+[\w-]+" ValidationGroup="CustomerInfo">*</asp:RegularExpressionValidator>
                    </td>


still trying to figure out what causes that.

I changed some code to use TwoColumn, that caused the problem. I cleaned up little bit in TwoColumn code, mainly delete some resources that I don't need any more, now the page loaded without any error.
