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
