How to add a FormToolbar with upload functionality to a custom form

Question

Hi all

I have a custom sharepoint form where I want to add a FormToolbar with upload functionality to it.

I added it like this

<SharePoint:FormToolBar runat="server" ID="ft" ControlMode="New" />

when I click on the attach file link it diplays a message saying "this form was customized not working with attachemnets".

I searched for this error and found that there is a fix and a method to make this work with a custom NewItem.aspx, the workaround was to modify the XSL.

My page is custom and has no XSL the fix is not applicable for me.

so is there a solution to this ?

thanks
