The code changes you inserted did fix the the date type issue and it does insert the order dates. However, I still can't make any other changes to either the summary or details server behaviors without it reverting to a text type. This is a real problem with version 5.
Are there other ways to get the current date into a mysql date field that Ecart v5 will accept? I'm not stuck on the hidden field solution. It always worked in the past and this will certainly need to be addressed in an update, but for now I just need a way to be able to edit the server behaviors without breaking the inserts.
Thanks for the help and I look forward to getting this solved.
