Alfresco JavaScript - How to get list of allowed values of a node property?

Question

I'm doing something like this:

document.properties["my:customProperty"] = getSomehowTheProperty(document);

my:customProperty is a string, which has some allowed values in the content model.

How can I get the allowed values from the content model, so that I don't have to store them in a JavaScript array inside the script?

Or how else can I check, that the function getSomehowTheProperty returned an allowed value?

I tried to wrap it with try-catch:

    try {
      document.properties["my:customProperty"] = getSomehowTheProperty(document);
      document.save();
    } catch (e) {
      document.properties["my:customProperty"] = "Default Value";
      document.save();
    }

But it looks like integrity is checked and th error is thrown at the end of executing the script, not inside the try block.

Googling "alfresco js allowed values of node properties" and similar queries gives me nothing.

In order to get that sort of information, you'll have to use the DictionaryService to get the PropertyDefinition

Off the top of my head, you'll want to do something like:

QName customPropertyQ = QName.createQName("my:customProperty", namespaceService);
PropertyDefinition customPropertyT = dictionaryService.getProperty(customPropertyQ);
List allowedValues = customPropertyT.getConstraints();

That'd be in Java, see this blog post for details on how to work with the DictionaryService from JavaScript
