  myArray = [];
  myStruct = {};
  myImage = imageNew("", 1, 1);
  mySpreadsheet = spreadsheetNew("mySheet");
  writeOutput(isObject(myPDF) & isObject(myQuery) & isObject(myXML) & isObject(myArray) & isObject(myStruct) & isObject(myImage) & isObject(mySpreadsheet));
</cfscript>

Can the title please be changed to: [ANeff] Bug for: isObject(image) and isObject(spreadsheet) and isObject(file) return YES Updated repro which shows isObject() returns YES for a file object: <cfscript> cfhtmltopdf(name="myPDF") {writeOutput("foo");}; myQuery = queryNew("myColumn"); myXML = xmlNew(); myArray = []; myStruct = {}; myImage = imageNew("", 1, 1); mySpreadsheet = spreadsheetNew("mySheet"); fileWrite(expandPath("./myFile.txt"), "foo"); myFile = fileOpen(expandPath("./myFile.txt")); writeOutput(isObject(myPDF) & isObject(myQuery) & isObject(myXML) & isObject(myArray) & isObject(myStruct) & isObject(myImage) & isObject(mySpreadsheet) & isObject(myFile)); </cfscript> Thanks!, -Aaron

On a similar note: While testing this and using CF 10,0,17,295085 Developer (Windows), I noticed that isPDFObject() returns different results depending on whether the PDF was read from a file or generated in memory. PDFs generated in memory return "no/false". (My tests reveal that the in-memory PDF is a "binary/byte[]" type.) <cfdocument name="varPDF" format="pdf"> <cfoutput>This is a PDF</cfoutput> </cfdocument> <cfpdf name="filePDF" source="c:\test.pdf" action="read"> <cfoutput> isPDFObject(varPDF) = #isPDFObject(varPDF)# (Should be Yes)<br> isPDFObject(filePDF) = #isPDFObject(filePDF)# (Should be Yes) </cfoutput>

James, I raised another bug, CF-4179264, to track reported inconsistencies in isPDFObject() For the rest of the cases, isObject returns NO. isObject returns True/YES only for ColdFusion objects.

This probably needs reopening as the implementation is still not quite correct: <cfoutput>#isObject(javacast("null", 0))#</cfoutput> Outputs: Yes It seems to me that the implementation is just wrong, because this check should simply be checking if the argument is an instance of whatever underlying class represents a CFC instance; which NULL - and all those other types - are not. It seems like it's going "is it one of these? No, good. What about one of these? No. OK... one of these? No. These? [... etc]" through a long list of types and once it gets to the end is going "OK, maybe it's a CFC instance.
