I’m using the Store Content method to store a file into an nt:unstructured node in my CRX repository. I want to add custom properties to that node. All the custom properties I add end up being strings which is inconvenient because some properties are dates and this will inhibit selecting nodes using a date range. The Sling POST servlet documentation indicates that you can provide type hints for custom properties however I can’t seem to get this to work using the Content Repository DSC.
