Select file was not found" error

I blogged about it long time ago but lost that post in a server crash. This error occurs when you try to attach a file in InfoPath task form. There are several solutions. One is as following: Open WrkTaskIP.aspx from the following location: C:\Program File\Common Files\Microsoft Shared\web server extensions\12\Template\Layouts Locate following tag: <asp:Content ContentPlaceHolderId="PlaceHolderMain" runat="server"> Insert following line before the end tag "</asp:Content>": <script type="text/javascript">aspnetForm.encoding = "multipart/form-data";</script>
