Hi dear grass users,

Thank you for your help.

I'm trying to get two field name of an attribute table (ctx_map) by the options of the gui. But I can access only at the first one and I don't find why...??. See my code below :

Dear Frank,

Hello Nikos,

if you refer to the last two "column" options,
how do you try to access these, in the script?

Like,

options['ctx_wf']
options['ctx_wtg']

Absolutely

?

Also, what .xml does

x.ScriptName --interface-description

generate?

There is no error on compilation, and help tab display Flags and Parameters information, like (french accent are not well encoded):

Parameters:
obj_map=name [required]
Name of vector map
MH ou WTG projet
obj_layer=string
Layer number or name

Default: 1
obj_name=name [required]
Nom de l'objet
*ctx_map=name [required] **
**Name of vector map **
*Contexte éolien *
**ctx_layer=string **
**Layer number or name **

**Default: 1 **
**ctx_wf=name [required] **
*Nom du parc *
**ctx_wtg=name [required] **
*Identifiant éolienne

Vector features can have category values in different layers. This number determines which layer to use. When used with direct OGR access this is the layer name. **Vector features can have category values in different layers. This number determines which layer to use.

Ah, and what does `x.ScriptName --ui` return?
Maybe an encoding related issue? Related entries in trac:

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 : 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...

Perhaps there is something, and experienced developers will notice it fast.
Yet, why don't you share a minimal working code? At least the interface,
so I can try myself to compile. Even in private if you
prefer. I am willig to help in understanding this error. So I will learn
about it as well.
