Mantid crashes when workspace with data displayed is overloaded

Reported by: Karl Palmen Owned by: Dan Nixon
Priority: major Milestone: Release 3.3
Component: Framework Keywords:
Cc: arturs.bekasovs@… Blocked By:
Blocking: Tester: Roman Tolchenov

Description

If I run 

LoadMuonNexus("emu00006473.nxs", AutoGroup=True, OutputWorkspace="emu_no_groups")

then display the data in the workspace, leave the data displayed and run 

LoadMuonNexus("emu00031895.nxs", AutoGroup=True, OutputWorkspace="emu_no_groups")

Mantid crashes on Windows 7 at least.

The two Nexus files are found in the AutoTestData folder and the systemtest data folders respectively.

  • Owner set to Anyone
  • Status changed from new to assigned

The only crashes with the colour fill plot, the 1D plot is fine.

This is a situation where you are replacing a Workspace2D with a group workspace, and it therefore rare.

Check new workspace for MantidMatrix is not a group workspace

Added check to ensure that cast to MatrixWorkspace does not return null.

If null is returned then close the matrix window and issue a warning to the log.

Following the original steps now causes the window to be closed when executing the second LoadMuonNexus, after which both workspaces appear in a group and can be opened and viewed normally.
