I am using DNN 5.2.3 and DMX 5.2.2 on a test (localhost) configuration in preparation for a DNN4.5.5 and DMX3.5.5 upgrade. When using DMX 5.2.2 on DNN 5.2.3 I am having a problem when adding a new custom attribute field of type 'Date'. The interface does not allow the date to be populated in the field manually or when using the pop up calendar control. This problem exists in two scenarios-- when upgrading the DNN and DMX versions in place or when installing DMX 5.2.2 on a new fresh DNN 5.2.3 install. We must be able to record an Issue and Expire Date for our documents. Any help would be appreciated.
