I was trying to adjust a line shape on my workflow surface and started getting "Valuecannot be null, Parameter name: Component" error. Now I can't even select the line as I keep getting this error as soons as I click on the line shape.
What are my options here? Do I have to discard the workflow and recreate it? Any insight is highly appreciated.
When I click on "ok" to see the error details, I get the following:
at System.ComponentModel.Design.SelectionService.System.ComponentModel.Design.ISelectionService.SetSelectedComponents(ICollection components, SelectionTypes selectionType)
at SourceCode.Workflow.VisualDesigners.ProcessDesigner.SelectObject(Object lineOrActivityOrEvent, Boolean fromSelectionChangedEvent)
