Product and version:
FileMaker server 16
When building a CWP using FileMaker PHP API, if you have a field with a dot in it's name
[ For example: Customer . ID ] the set field option will always return an error "field is missing"
How to replicate:
1- Create a field with a dot in it's name [ Customer . ID ]
2- Use the set field option in a PHP code [ $upd_rec -> setField ( 'Customer . id', "" ); ]
Remove the dot from the field name
