nodetool: track layer of selected feature instead of current layer (fixes #7351)

History

#1 Updated by Salvatore Larosa over 7 years ago

Hi Nathan,
I can't reproduce here, Linux and QGIS master.

I suppose it occurs on Windows machine.

#2 Updated by Regis Haubourg over 7 years ago

Confirmed here on Widows 7 and revision 32de07d..

#3 Updated by Borys Jurgiel over 7 years ago

Confirmed on Linux/master, only when OTFR enabled:

1) Add a vector and a raster layer, ENABLE OTFR
2) Activate the edit mode, then the node tool and SELECT ANY FEATURE
3) Choose the raster layer in TOC. Edit tools become grayed, but the mouse cursor is still cross.
4) Click wherever on the map -> crash

The crash doesn't happen with OTFR disabled.
The crash doesn't happen until one of features is in edit node mode.

  • Subject changed from Crash with node tool when raster enabled to Crash with node tool when on the fly CRS transformation enabled
  • Crashes QGIS or corrupts data changed from No to Yes
  • Category changed from Rasters to Digitising
  • File nodetool.png added

ok, with the above steps I can confirm it.
it is not needs to load a raster layer.

Also, the nodes have shifted (see image)
