Issue: Why are some dates spontaneously changing? I’m sure I entered them correctly.
Description: This problem only occurs for a user with an Access interface and MySQL back end database who is using a date format different from the standard US date format of MM/dd/yyyy (month/day/year). This problem was reported by a user whose date format is dd/MM/yyyy (day/month/year).
When the date format is dd/MM/yyyy, the Access interface sometimes saves dates incorrectly. It does this for dates where switching the day/month order creates a valid date, i.e. 1/2/14 and 2/1/14 are both valid dates, but 22/10/2014 is not a valid date in the MM/dd/yyyy format and will always be correctly saved as October 22nd if you are using the dd/MM/yyyy format.
For a user who originally had a MS Access back end (jcms_db.mdb), this problem began after converting your MS Access back end to a MySQL back end. Starting with Access interface version 4.6.0 conversion to a MySQL back end was required.
Not all dates are saved incorrectly. For example, the Add Mouse form is saving the dates correctly but the Edit Mouse form is changing the birth date.
Fix: Note that the date format is a Windows setting which can be changed by going to the Control Panel – Region and Language – Change the date, time, or number format. Set the Short Date to M/d/yy or MM/dd/yyyy. Now dates will be saved correctly. Any incorrect dates will need to be fixed manually. It is expected that this problem will be fixed in Access Interface version 6.1.9.
Issue: JCMS MySQL Converter: After converting a JCMS v4.2.x database to MySQL, only one mouse can be added into JCMS.
