[Okular-devel] Okular with Goldendict Ubuntu 11.10

[babusce]

Hi, my name is Sonia (Italy).
I like very much Okular and I would like to use for read PDF books and
documents in english format.
Sometime, I must translate a word, then I would like to use Goldendict. 
In my installation I have the two software(Okular-Goldendict)  but when
I do "double cick" on Okular-PDF word, Goldendict doesn't work.
Must I use another compatible-software with Okular or plugin? 
Many tks 
Sonia
