Allow search for process definitions without versionTag

XMLWordPrintable

      Use case:
      I write a migration plan for my process instances.
      We did not set a versionTag in the beginning, so I have several old instances running with null for the version tag.
      The new target definition comes with version tag 1.

      To build a migration plan, I need the sourceProcessDefinitionIds of all instances running on a versionTag equal to null.

      However, I can not query for those definitions, because a query parameter null is not allowed for versionTag.

      Suggestion:
      Since having a null version tag is common, allow querying for it with a new query method withoutVersionTag.

        This is the controller panel for Smart Panels app

          1.
          		 In the Java API, I can search for process definitions without version tag Sub-task Closed Unassigned
          2.
