Was fitting happily in an (unspecified) earlier version of !SasView which then just ''""stopped working""'' (wouldn't open anymore). So upgraded to 4.1.2. Data loads in 4.1.2 but on attempting a fit this is returned: {{{ Error(s) Occurred: > Traceback (most recent call last): > File ""sas/sasgui/perspectives/fitting/fit_thread.pyc"", line 82, in compute > File ""sas/sasgui/perspectives/fitting/fit_thread.pyc"", line 14, in map_apply > File ""sas/sasgui/perspectives/fitting/fit_thread.pyc"", line 11, in map_getattr > File ""sas/sascalc/fit/BumpsFitting.pyc"", line 275, in fit > File ""sas/sascalc/fit/BumpsFitting.pyc"", line 375, in run_bumps > AttributeError: 'FitDriver' object has no attribute 'fitter' }}} This looks remarkably similar to #1061 which is only classified as minor, however Judith says this is stopping her from doing any fitting. She also comments that ''""The first error occurs after I choose the model (not clicked on Fit yet)""''. If you look carefully at the screenshots you will note two slightly different errors. So am initially marking this as a blocker pending further investigation as it appears a more serious and widespread problem than in 1061. @pkienzle has commented: ''""There is an error in bumps, but it isn't being properly reported because of an error in the bumps wrapper. I can arrange it so that the next bumps release fixes the wrapper error but I can't address the bumps error without being able to reproduce it.""'' Data and screenshots from Judith to assist diagnosis are attached." defect assigned blocker SasView 4.3.0 SasView SasView Bug Fixing
