Custom SharePoint 2010 designer page throws "The data source control failed to execute the insert command" exception while adding the new item after the August 13, 2013 CU has installed

Question

We have the SharePoint Server 2010 with SP1 environment on which the custom SP2010 designer pages were working as expected before the
August 13, 2013 CU has installed. But, getting the below exception while trying to add the new item after the CU has installed.

I have tried changing the "DataSourceMode" as below, now the insert command is working, but update command is not working.
<SharePoint:SPDataSource runat="server" DataSourceMode="ListItem" />
Also, the lookup dropdown fields are displaying the value as "<a href="Daughterhttp://cpsp10/sites/Employees/_layouts/listform.aspx?PageType=4&ListId={8F62F444-FB6A-4F03-9522-C4696B45DCD1}&ID=10&RootFolder=*">Daughter</a>"
instead of only "Daughter".
Please provide the solution to get rid of this issue.
Thanks

Try below:

While there can be many causes for this generic error message, in my case the first parameter or ddwrt:DataBind function inside the SharePoint:FormFields element was
'i' and I was working with an Edit Form. Changing it to
'u' as it was with every other FormField fixed the issue.
<SharePoint:FormField runat="server" id="ff1{$Pos}" ControlMode="Edit" FieldName="Esittaja" __designer:bind="{ddwrt:DataBind('u',concat('ff1',$Pos),'Value','ValueChanged','ID',ddwrt:EscapeDelims(string(@ID)),'@Esittaja')}"
/>
Explanation:
DataBind operation type parameters (the first parameter) are listed below:
'i' stands for INSERT,
'u' stands for UPDATE,
'd' stands for DELETE.
