Validate document ID

Is there a way to validate an Appian document ID before trying to use the document() function on it?  document() will fail if passed an invalid Appian document, and todocument() will return a document type even if the ID is not a valid Appian document ID

  • What validation are you wanting to do?  Are you talking about a just-uploaded document, or a document ID for a document that may already be in the system if it exists?

    If it's the latter, my favorite way is to use the "getContentObjectDetailsById" function (from the Appian object information retriever plug-in), which will return a string value regardless of how valid the ID you pass in is, but when it belongs to a valid document the metadata it passes out can be used to tell for sure.
