PHP Edit command fails if "Not Empty" validation set
Operating system version
Mac OS X 10.8.5
Description of the issue
When using either of the 2 methods of editing an existing record in PHP, if there is any field on the layout referenced by the edit that has the validation "Not Empty" set, the edit fails without reporting any error message.
This is regardless whether the field in the field in question has data or not, whether it is that field that is being edited or not, or whether the "Always" or "Allow user to override during data entry" Validation flags are set.
Also, whether or not the field is being edited is irrelevant. That is the edit command may be modifying a totally different field and the edit still fails.
Steps to reproduce the problem
Set one or more fields on the layout referenced in a PHP edit command to have the validation "Not Empty" and then attempt to edit any record in that table using PHP.
The record is appropriately edited by PHP regardless of the "Not Empty" Validation settings of fields on the PHP Edit layout (unless the validation genuinely fails).
Interestingly "FileMaker::IsError($result)" does capture that an error occurred, but the "$result->getMessage()" is uninformatively blank.
Exact text of any error message(s) that appear
The problem is at the server end. All client device types and browsers reported the same issue.
Turn off "Not empty" validation on all fields on the PHP edit layout OR remove fields with the "Not Empty" validation flag set from the layout. Of course this means it is not possible edit such fields.
