Hi,

Thanks Arnaud, but it doesn't change anything for me, except that now I have 
to define a protocol parameter in my Vector constructor.

Do I need to load data when creating the layer? Currently I load my data later 
in the process (at the end of the page) as I need to load different data 
after the search process.

Y.
