Hi all, I'm on 17.05 galaxy version and display it on firefox. I'm trying to use "show structure" functionnality on my histories (I've never tried before this version) and I obtain this error : URL: http://192.168.100.98:8080/galaxy/history/display_structured File '/data/galaxy-dist/.venv/local/lib/python2.7/site-packages/weberror/evalexception.py', line 431 in respond app_iter = self.application(environ, detect_start_response) File '/data/galaxy-dist/.venv/local/lib/python2.7/site-packages/paste/recursive.py', line 85 in __call__ return self.application(environ, start_response) File '/data/galaxy-dist/.venv/local/lib/python2.7/site-packages/paste/httpexceptions.py', line 640 in __call__ return self.application(environ, start_response) File '/data/galaxy-dist/lib/galaxy/web/framework/base.py', line 135 in __call__ return self.handle_request( environ, start_response ) File '/data/galaxy-dist/lib/galaxy/web/framework/base.py', line 214 in handle_request body = method( trans, **kwargs ) File '/data/galaxy-dist/lib/galaxy/webapps/galaxy/controllers/history.py', line 571 in display_structured return trans.fill_template( "history/display_structured.mako", items=items, history=history ) File '/data/galaxy-dist/lib/galaxy/web/framework/webapp.py', line 891 in fill_template return self.fill_template_mako( filename, **kwargs ) File '/data/galaxy-dist/lib/galaxy/web/framework/webapp.py', line 905 in fill_template_mako return template.render( **data ) File '/data/galaxy-dist/.venv/local/lib/python2.7/site-packages/mako/template.py', line 445 in render return runtime._render(self, self.callable_, args, data) File '/data/galaxy-dist/.venv/local/lib/python2.7/site-packages/mako/runtime.py', line 829 in _render **_kwargs_for_callable(callable_, data)) File '/data/galaxy-dist/.venv/local/lib/python2.7/site-packages/mako/runtime.py', line 864 in _render_context _exec_template(inherit, lclcontext, args=args, kwargs=kwargs) File '/data/galaxy-dist/.venv/local/lib/python2.7/site-packages/mako/runtime.py', line 890 in _exec_template callable_(context, *args, **kwargs) File '/data/galaxy-dist/database/compiled_templates/base.mako.py', line 63 in render_body __M_writer(unicode(next.body())) File '/data/galaxy-dist/database/compiled_templates/history/display_structured.mako.py', line 50 in render_body __M_writer(unicode(render_item( entity, children ))) File '/data/galaxy-dist/database/compiled_templates/history/display_structured.mako.py', line 35 in render_item return render_render_item(context._locals(__M_locals),entity,children) File '/data/galaxy-dist/database/compiled_templates/history/display_structured.mako.py', line 191 in render_render_item render_item_job( entity, children ) File '/data/galaxy-dist/database/compiled_templates/history/display_structured.mako.py', line 183 in render_item_job return render_render_item_job(context,job,children) File '/data/galaxy-dist/database/compiled_templates/history/display_structured.mako.py', line 239 in render_render_item_job __M_writer(unicode( show_params.inputs_recursive( tool.inputs, params_object, depth=1 ) )) File '/data/galaxy-dist/database/compiled_templates/show_params.mako.py', line 293 in render_inputs_recursive for i, element in enumerate(listify(param_values[input.name])): TypeError: 'Undefined' object is not callable Is it a problem with this history (I've tested with a full green history and with history containing red jobs without difference in error message) or with my galaxy configuration may be ?
