[Actionframework-users] problem with the arrays

[<bm...@ho...>]

hi. While trying to receive an array of Strings I become the following =
errror:
Conversion error occurred when handling action '/grabarGaleria' (field: =
'txtimg'): org.actionframework.ConversionException: Unexpected =
exception; nested exception is: =
java.lang.ArrayIndexOutOfBoundsException: -1 < 0

the action node at the config xml file looks so:
<action name =3D "/grabarGaleria" method =3D "grabarGaleria(int =
idGaleria, String publicacion, String seccion, String idVisor, String[] =
txtimg)">
 <on-return value =3D "void" show-url =3D "url">
  <output-variable name =3D "url" value =3D =
"editarGaleria?idGaleria=3D$idGaleria&amp;publicacion=3D$publicacion&amp;=
seccion=3D$seccion&amp;idVisor=3D$idVisor" />
 </on-return>
</action>

and the java method:
public void grabarGaleria(int idGaleria, String publicacion, String =
seccion, String idVisor, String[] txtimg){
    // anything to do by the moment
}

in the velocity template I have 3 textfields called 'txtimg' (the number =
of the textfields should change but I have put a fix number just in =
order to test it)

Thx in advance
