Thanks Ken
I saved item after new attachment addition & also after removing the
old one.But no success.Attachment list not refreshed.
Also I don't want to save item (if the user cancels send then I will
have to remove this item from drafts).I reassigned the body
format,that refreshes the attachment list.But in plain text mode link
is not recognized (it is displayed as plain text) & cursor position
again set to starting of message body .
Is there any way so the link gets recognized & also cursor position
doesn't change? If I don't add new attachment ,just remove the old
one & add the link then there is no problem link is recognized &
cursor position also not changed.
