Description
Performing multiple cutting without saving after each cut results in loss of attributes of some features.
To experience the strange behaviour follow the steps:- load the shape (I used "color" field to categorize)
- Make 2 or more cuts with split feature
- Polygons not involved in splitting operation disappear
- after saving the polygons re-appear, but one of the splitted polygons has lost its attributes.
Last master on win7 64bit
Lisboa is not affected

- OS version deleted (
7 - 64bit) - Priority changed from Normal to Severe/Regression
- Operating System deleted (
Windows) - Crashes QGIS or corrupts data changed from No to Yes
If it is a regression is a blocker. I see this also on Linux so it should not be platform dependent.

The attribute part is linked to #7112
Here, it seems, the attributes are not lost, but rather that the form does not display the attributes (which can lead to loose the attributes if the form is confirmed). See the other ticket for more details.

Things getting worse. With the latest master, cutting feature with split tools causes,unexpected results after save layer editing:
- some feature desappear and get lost forever
- some feature duplicate
I have experienced this behaviour on a polyline shape converted from a dxf layer. During editing session, I used other editing tools: create new, node tool, simplify line tool.

I've tested the latest master (e7ea582) on win7. The problem is not solved. It's important to make multiple cuts over the same features without saving. After some cuts the message "Already active iterator on this provider was closed" appears on Log Message and one of the features created by cut operation has lost its attributes.

Maybe I am wrong, but I dont see any loss of attributes.
If the layer is not categorized you can see the new split geometries,
when the layer is categorized the geometries are not displayed but they are into attributes table.
The sample data has a categorized style with already set values so just add a default without any value to display the new split geometries.

ahhh! I missed it! :)
you are right, there are no missing or lost features, but there are still missing/lost attributes.
try do multiple splits before saving.
You will sew that the column "colore" should be filled with all "1" (the original attribute) but it is not.
