Nuxeo Studio, LTS 2021 Button > Document Actions Slot > Activation Filter > Custom Expression

Dear Experts,

I have a custom schema ("Validation") that has a Yes/No field called "Validated".  The schema is attached to a document type called "MedicalRecords".  I want to be able to toggle a button in Document Actions Slot if the value Validation.Validated is Yes.  What is the correct syntax for custom expression to enable / disable this button?  I have tried document.properties.validation.validated === null and various other combination.  Any guidance would be appreciated.

Thanks,

SG

The custom expression syntax must be valid JavaScript, not Polymer flavored e.g.:

document.properties['validation:validated'] === 1

Thank you @Josh-F-Hyland 

When I look at the JSON, I see the following:

"properties": {
"Validation:Validated": "No",
"google_ml:imageTextDetection_content": null,
},
"google_ml:speechRecognition_language": null,
"google_ml:speechRecognition_confidence": null,

I am curious as to why Validation schema shows up under "properties" but other schemas do not? 

I appreciate the help!

The REST API allows you to control which schema values are returned via the "properties" header:
