  How to check if a property value is readonly using extendscript?

  Posted by Miguel De mendoza on August 2, 2015 at 12:26 pm

  I’m writing a script that collects all properties from a layer and write them into an XML file. When I retrieve the values from the XML,
  some values are readOnly and the toolkit throws an error.

  Is there any way to check it, like readonly attribute on File object?
  ie: layer.property().(readonly||readOnly)

  If not, someone can tell me wich aproach can I take to go in the right direction?

  Whether an attribute is read-only or read/write is documented [link].

  That said, you could use try/catch [link] to attempt to change the value of a property and recover if it fails.
