<p><a class="issue tracker-1 status-5 priority-5 priority- closed" href="https://issues.qgis.org/issues/7225" title="QGIS crashes after failed intersect removal (Closed)">#7225</a></p>
<p>but the user is not allowed anymore to digitize an adjacent polygon digitized against an invalid existing one, and the error message ("The feature cannot be added because it contains an emtpy geometry") is misleading.</p>
<p>So this case (new in QGIS master, AFAIK) needs</p>
<p>a) a different error message</p>
<p>b) possibly an option that won't allow to add invalid features in the first place</p>
<p>I'll tag this as blocker because it was introduced a new behavior (not allowing digitize an adjacent polygon against an invalid one, with the "avoid intersection" option) that does not work as expected and it is misleading for users.</p> QGIS Application - Feature request #7235: Add option to avoid users producing invalid topologies while digitisinghttps://issues.qgis.org/issues/7235?journal_id=415752013-06-02T00:09:46ZGiovanni Manghigiovanni.manghi@gmail.com
