Hello List
I have a process that works perfectly in Brighton 2.6.1 but is broken in Wien
2.8.2.
I have two Postgis polygon layers loaded in QGIS - MR and RC.
I copy some polygons from Ordnance Survey MasterMap Topography layer and paste
into a memory layer. In the memory layer the polygons are merged and edited
until correct. Then this new polygon is copied into MR (there are three
mandatory fields which have to be filled at this point). When I save my MR
edits a series of triggers in the database update various fields (area, x, y,
centroids, etc). Then I copy the new feature(s) in MR and paste into RC.
Polygons are merged if required. Again, a series of triggers on the RC table
update some fields.
There are three processes that throw errors in 2.8.2
1. Selecting a polygon in MR and using the node tool to edit and move
nodes fails with a "could not snap to feature in current layer" error. QGIS
will crash with data written to a minidump file after selecting node tool,
selecting a node and dragging it. Crash on release.
2. Selecting overlapping polygons in MR and RC and using the "cut with
polygon from another layer" tool to cut RC with MR. That returns the error
below:
An error has occured while executing Python code:
Traceback (most recent call last):
File "C:\Users\me\.qgis2\python\plugins\DigitizingTools\tools\dtcutter.py",
line 94, in process
bbox = cutterGeom.boundingBox()
AttributeError: 'NoneType' object has no attribute 'boundingBox'
Python version:
2.7.4 (default, Apr 6 2013, 19:54:46) [MSC v.1500 32 bit (Intel)]
QGIS version:
2.8.2-Wien Wien, 1b929ef
3. Pasting from MR into RC does not carry over attributes (the field names
are the same) and the triggers don't run on the RC table.
While this is very probably user specific we'd appreciate any suggestions.
Thanks in advance
