Cannot Publish SharePoint 2013 Workflow using SharePoint Designer

When trying to publish SharePoint 2013 Workflow using SharePoint designer 2013, sometimes the following exception appears:

Microsoft.Workflow.Client.ActivityValidationException: Workflow XAML failed validation due to the following errors:
Cannot set unknown member 'CompositeTask.RelatedContentLinkListItemIntegerId'. HTTP headers received from the server - ActivityId: 15459ce7-8e0d-4267-aa59-cc724289e422. NodeId: TECSRVSOL02. Scope: /SharePoint/default/c8ca3a4c-bb1a-4056-b675-597fa0348916/0d4731cd-bfe2-47b6-acd2-6caa6bd45931

I tried so hard to find a solution for this until I found this post (http://sp2013-blog.com/2013/04/solution-errors-were-found-when-compiling-the-workflow-the-workflow-files-were-saved-but-cannot-be-run-cannot-set-unknown-member/) Michael and the following Post by Tarek Yehia (http://sharepointserver-2007.blogspot.ae/2013/04/sharepoint-designer-error-while.html).

Basically, The solution was to register Workflow service again using SharePoint 2013 Power Shell.

Register-SPWorkflowService -SPSite 'https://myhost/mysite' -WorkflowHostUri 'https://workflowhost' -AllowOAuthHttp -Force

SharePoint 2013 Workflows (Loops and State Machine)

Finally, SharePoint 2013 supports a state machine workflow. It is not mandatory to be sequential. Also, It supports loops now, so you can create loop without the guilty feeling of the workaround developers were doing in old SharePoint servers. Good Job.
In the image below, you can add go to another stage in the "transition to stage" scope. You have to configure Workflow Manager 1.0 and register the workflow service to the SharePoint 2013 Server.
