I have an infopath form which was working fine until recently (2nd time this has happend - another form did the same a while ago and I rebuilt from scratch).
The form collects the dropdown list from a data connection (SQL database) and has rules attibuted to the field to populate additional relative data fields. There are follow on entry fields and some datepicker fields (Date From and Date To). Should be simple !
After several weeks of working fine, the list began to default the dropdown list to the very last item in the data set as default, if you chose another item in the list it would revert back to the last (as thought it had submitted and reset).
I have solved the defaulting to last item by setting the 'postback settings' to Never, however the rules do not populate the additional fields (as the form is not telling sharepoint anything has been entered). Also the data which has been selected gets cleared when you progress down the form to the datapicker and enter a date.
The data connections are local site .udcx, which I have deleted and re-created as new data connections to repeat the same issues.
This indicates that this is within the form or list?
Any guidance would be appreciated as I do not want to have to re-create the whole form and ruleset again :-(

NB, works fine in preview !
Note2: Added a default value into the dropdown list field and it now defaults to the first item in the data connection list.
