In the previous version of CloudForms Management Engine, deploying a heat stack to multiple providers as a bundle catalog item would fail with a HTTP/1.1 400 Bad Request error. This was because the CatalogBundleInitialization and CatalogItemInitialization methods used in this case were not able to handle orchestration provisioning. They were originally designed to work with VM provisioning, before orchestration provisioning was introduced to the product. This bug was fixed by updating these methods to handle orchestration provisioning correctly. Users are now able to deploy the heat stack as a catalog bundle item in the new version of CloudForms Management Engine.
