Rewriting old workflow rules with conditional transitions in the statemachine

Hello,

I am afraid, the current version of workflow does not support this scenario out of the box. As a workaround, I suggest you create a separate field value, for example:

    Testing: {
      transitions: {
        finish: {
          targetState: 'TemporaryState'
        }
      }
    }

Then, you can extend this logic and select the required value after setting TemporaryState. For this, use the onChange rule. For example:

var entities = require('@jetbrains/youtrack-scripting-api/entities');
exports.rule = entities.Issue.onChange({
  title: 'Automatically-change-temporary-state',
  guard: function(ctx) {
    return ctx.issue.fields.becomes(ctx.Status, ctx.Status.TemporaryState);
  },
  action: function(ctx) {
    var issue = ctx.issue;
    var fs = issue.fields;
    if (fs.MergedToDevelop === null)
      fs.Status = ctx.Status.Finishing;
    else
      fs.Status = ctx.Status.Merging;
  },
  requirements: {
    MergedToDevelop: {
      type: entities.Field.stringType,
      name: 'Merged to develop'
    },
    Status: {
      type: entities.EnumField.fieldType,
      name: 'Status',
      TemporaryState: {
        name: 'TemporaryState'
      },
      Finishing: {
        name: 'Finishing'
      },
      Merging: {
        name: 'Merging'
      }
    }
  }
});

I hope it will be helpful. Should you have any further questions, feel free to contact us.
