Yes exactly<br>

f = QgsFeature()<br>
iter = vectorLayer.getFeatures( QgsFeatureRequest() )<br>
while iter.nextFeature( f ):<br>
print f.id()<br>
f.setAttribute( field, QVariant( 1 ) )<br>
vectorLayer.updateFeature( f )<br>
<br>
Prints only 1 id, commenting the last line prints all ids.<br>

Hi all,<br>
<br>
I am looping over features of a layer using new API
(QgsFeatureRequest).<br>
If I modify a feature and do: layer.updateFeature(f), my
loop is broken.<br>
Is this a normal behavior?<br>
<br>
What should I do if I want to modify features during the
loop?<br>
<br>
Thanks<br>
<br>
Denis<br>
