Bug with Workflow Manager parameters section

New Contributor

It appears that if you have a workflow.xml file which has a workflow parameters section with only One Parameter entry, that the Ambari Workflow Manager will fail to be able to load this file.

I was even able to reproduce the problem by starting with a workflow, adding a single workflow parameter and saving the workflow. This process succeeds and viewing the XML showed the proper syntax for one parameter, but then when I closed the workflow and tried to reopen it with "Recent", it failed to load.

The problem goes away with 2 parameters -- so it appears to be some sort of zero-indexing problem (I think).
