Force dd own mapping take in on nomodifiable buffer

Hi,



Assuming that the nomodifiable option is set on a buffer, I am trying to map this kind :

nnoremap <script> <silent> <buffer> dd
\:call explorer#UniteDeleter(get(b:array,line(".")),1)<CR>



But vim returns to me the nomodifiable option forbid the dd action.

How can I force that ?

Thank you
