I added rasters a mosaic data set by using a wildcard filter on a folder (example *abc*) to add a subset of the files. I added a new file to the folder that meets the filter criteria. When I synchronize, I gives and error "Completed crawling 0 data source items" and the mosaic dataset is not updated. If I do the same with no filter (i.e loading all the files in the folder), synchronization works. Any ideas about what is going on?
