i am getting the above error when I am trying to override WorkflowHistoryList.ascx using a virtual path provider. Has anyone else come across this and found a solution? Is there any more tried and tested way of making the workflow history list more user friendly
Can we see how you configured the virtual path provider and the virtual path mappings?

Are you following this approach or doing something different?
