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

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

            Hi jan.galinski@holisticon.de,

            thanks for the request.

            This sounds like a reasonable addition to the ProcessDefinitionQuery.
            I will rephrase the feature a little bit and go for adding an option that allows to search for definitions without versionTag rather than removing the null-check.
            I hope that is fine with you.

            As usual, if you would like to speed up the integration of that feature we are always happy about code contributions via pull requests.

            Thanks again.

            Best,
            Tobias
