Description (last modified by Martyn Gigg) (diff)

When running the following script the first call to getNumberParameter is successful but the second fails. 

w1 = LoadEventPreNeXus(EventFilename="../../../Test/Data/sns_event_prenexus/CNCS_7850_neutron_event.dat", OutputWorkspace="w1")
w1_inst = mtd.getMatrixWorkspace("w1").getInstrument()
print w1_inst.getNumberParameter("scale-factor")

w2 = LoadEventPreNeXus(EventFilename="../../../Test/Data/sns_event_prenexus/CNCS_7850_neutron_event.dat", OutputWorkspace="w2")
w2_inst = mtd.getMatrixWorkspace("w2").getInstrument()
print w2_inst.getNumberParameter("scale-factor")

(In [5648]) Add call to populate the parameter map in the locally created workspace to LoadEventPreNeXus. If this is not done a second load of the instrument clears the map. Re #1472

In 6406 this seems to be fixed. I think this is a consequence of changeset [6109].

Marking as fixed.

the script above works in [7139], since the parameter map is now reloaded into the workspace even when the instrument is taken from the cache.
