I have created a custom ribbon button that initiates a workflow, but the workflow is only designed to work on one item at a time. Even if it weren't, it appears that SharePoint doesn't handle this situation well. Not only will it not work with multiple items selected, it won't work with one selected! Does anyone know of a way to make this work? Maybe it could start multiple instances of the workflow, or pass a list of selected items to be dealt with in the workflow somehow? Bear in mind, I am not able to use any code to do this- only OOB solutions.
