Hi all!

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!
