[galaxy-dev] galaxy.tools.parameters.basic.RuntimeValue not str

Hi all! Maybe somebody faced with this problem: 1) in my wf used tool with: "u'model_class': u'Conditional', u'type': u'conditional', u'name': u'reference_genome'}], " 2) when i run wf via web - all ok, and on a second step: "Select a reference genome" is "test" (in view details) But, when i run wf via api: param = {u'mapper_easy' :{u'param': u'reference_genome|index', u'value': u'test'}} nuser.workflows.run_workflow(workflow_id=wf_id, dataset_map=dataset_map, params=param, history_id=hist_id) wf started and on a second step is failed... In details: "Select a reference genome" is "<galaxy.tools.parameters.basic.RuntimeValue object at 0x7f5374266850>" Any help is appreciated. Thanks!
