I am pretty new to coding and have pulled the majority of my code from examples that I've seen online via the community. For the most part I've learned lots and have a functioning page that works how I envisioned. However, there is (1) field that is causing me grief. 

I am using VisualStrap: http://blogforce9.blogspot.com/2013/12/visualstrap-visualforce-implementation.html 
&
I am using his Modal idea: http://blogforce9.blogspot.com/2014/06/visualstrap-using-modals-in-visualforce.html

All seems to be working very well except the Due Date field (due_date__c). It will not update the field value in the panel when Save is clicked on the Modal. All other fields update upon Save in the Modal as expected. Due Date will not.

I am just stumped. When I update the Due Date in the modal and click save, nothing happens. No changes are written to the record. I manually refresh the page and affirm that no changes have been written. If I select any other field in the Modal it updates the record when I click save on the Modal.

Any suggestions? Please let me know if something doesn't make sense...there is a lot of code that was truncated, I don't think I left anything vital out.

Thanks.

I am just stumped. When I update the Due Date in the modal and click save, nothing happens. No changes are written to the record. I manually refresh the page and affirm that no changes have been written. If I select any other field in the Modal it updates the record when I click save on the Modal.

Any suggestions? Please let me know if something doesn't make sense...there is a lot of code that was truncated, I don't think I left anything vital out.

Thanks.
