In my Locus GIS project I´ve a shapefile (type point) to colect animal species. In on of the shapefile´s field I´ve a list of species that the user most select.
The problem is, when he´s going to colect a second point, the register of the first point still there in the field, and not a blank field.
the 'Enumeration' atribute has two modes. As default is used "last used" but you can also use any value from the list as default value. So if I understand you correctly you require as default option something like "No Value"? Basically the possibility skip such attribute and do not add any value, am I right?
Thanks, Petr

Dear Petr,
Thanks, one more time, for your help.
Ah ok!
If i understand it right, in my XML file, if i put <default>''</default> the new data point will appear blank?

I think that you could use 'space' as value. Like
<attribute type="ENUM">
<id>Observacao_1</id>
<label>Observacao_1</label>
<required>1</required>
<editable>0</editable>
<default> </default>
<options> |Anf-Alytes cisternasii|Anf-Alytes obstetricans|Anf-Anguis fragilis|Anf-Bufo bufo|Anf-Bufo calamita
</options>
But it isn't ideal and it isn't 'null'. We should focus on it and prepare valid solution for 'non value' option

My xml is like this
<attribute type="ENUM">
<id>Observacao_1</id>
<label>Observacao_1</label>
<required>1</required>
<editable>0</editable>
<default> </default>
<options>|Anf-Alytes cisternasii|Anf-Alytes obstetricans|Anf-Anguis fragilis|Anf-Bufo bufo|Anf-Bufo calamita
</options>
As you can see, my first value is Null (i put the | first).
How can i do the same in the Default_Value?
