Hello Nikos,

x.myscript --ui just launch the gui box.
I have found a trick to run the script. Actually I need one field from 
on vector table and 2 fields from an other vector table. like that it 
works :

#%option G_OPT_V_MAP
#% label: MH ou WTG projet
#% required : yes
#% guidependency: layer,obj
#%end
#%option G_OPT_V_FIELD
#% guidependency: obj
#%end
#%option G_OPT_DB_COLUMN
#% key: obj
#% description: Nom de l'objet
#% required: yes
#%end


#%option G_OPT_V_MAP
#% key: ctx_map
#% label: Contexte éolien
#% required : yes
#% guidependency:ctx_layer,ctx_wf,ctx_wtg
#%end
#%option G_OPT_V_FIELD
#% key:ctx_layer
#% guidependency:ctx_wf,ctx_wtg
#%end
#%option G_OPT_DB_COLUMN
#% key:ctx_wf
#% description: Nom du parc
#% required: yes
#%end
#%option G_OPT_DB_COLUMN
#% key:ctx_wtg
#% description: Identifiant éolienne
#% required: yes
#%end

But as soon as I try to name myself the first table by Key parameter 
like #%key : obj_map and add key name at layer (like in the second part 
of the code) It does not work anymore... It looks like the fisrt map is 
automatically named "map" by the gui. I don't mind but I find this 
strange. I'm sure there is a explanation,somewhere...
Cheers,
Frank
