How to check whether the current workflow is valid? Is WorkflowDesigner.IsInErrorState() working?

Question

How to check whether the current workflow hosted in a workflowdesigner is valid?

I tried calling WorkflowDesigner.IsInErrorState() everytime WorkflowDesigner. ModelChanged event fires.. but it always return false (ie no error) even though I see the red error sign in the designer!

any idea?

you can use ActivityValidationService directly
