Hi,
After upgrading to SharePoint 2013, custom workflow actions are not working. If I open the workflow in SharePoint Designer 2013 I see the below:
then Error message: Could not deserialize object. The typ...
The error reads: Could not deserialize object. The type 'DT.SP2010.WorkflowActivities.Library.CancelWorkflow' could not be resolved.
The action is still available in the Action menu and if I add the action again to the workflow it gives me the below errors when I try to Publish (save and check for errors was fine):
(0, 10) The type or namespace name 'DT' could not be found (are you missing a using directive or an assembly reference?))
(119, 16) The type or namespace name 'DT' could not be found (are you missing a using directive or an assembly reference?))
Custom actions were deployed using Solution (no manual file placement). To deploy it on 2013 server I downloaded it from 2010 and installed using "Install-SPSolution -Identity dt.sp2010.workflowactivities.wsp -WebApplication "SharePoint - 80" -GACDeployment -CompatibilityLevel {14, 15}'
Any help will be much appreciated.
