split feature - Bug in copy attributes

[beltegeuse]

Hi all, I use QGIS for one month and i think it's a good soft but there is a problems with the split feature. Explain :

1. You have a feature with attribute and id (ex : 3660)
   
2. You split these feature so you have two features. (The original feature with id = 3660 and the new feature id = -1).
   
3. You split the new feature (id = -1) so we have three features (id : [3660,-1,-2]).
   
4. You split one once again the feature (id = -1) so you get a feature with the id is -4. You have 4 features.
   

=> And when your commit change, your feature (old id = -3) have no attribute.

it's link with QgsGeometryMap. QgsGeometryMap bug when featureId is negative. To have a different issue :

In qgsvectorlayer.cpp : in splitfeature fucntion : remplace :

mChangedGeometries.insert(select_it->featureId(), *(select_it->geometry()));

by :

if(select_it->featureId()<0)
{
   
}
else
{
 mChangedGeometries.insert(select_it->featureId(), *(select_it->geometry()));
}
