DocumentMode invalid enumeration

[Ghoulfool]

I noticed an old script no longer works on CC

  if (app.activeDocument.mode == DocumentMode.INDEXEDCOLOR)
  {
   // blah blah
  }

I got the error 1320 Invalid enumeration value, but I'm pretty sure that's valid code. So what's up Photoshop?

Whereas I got round it by evaluating as strings:

  var m = app.activeDocument.mode;
  if (m == "DocumentMode.INDEXEDCOLOR")
  {
   // blah blah
  }

Any ideas?

Using DocumentMode.INDEXEDCOLOR directly worked fine for me just now on OSX with CC 2018.

What OS and Photoshop version are you using?

i cannot reproduce your problem with PS CC 19.1.3

I tried:

if (app.activeDocument.mode==DocumentMode.GRAYSCALE) $.writeln ('GRAY')

if (app.activeDocument.mode==DocumentMode.RGB) $.writeln ('RGB')              // actually correct result

if (app.activeDocument.mode==DocumentMode.INDEXEDCOLOR) $.writeln ('INDEXEDCOLOR')

No idea what's going on with your version

Are you sure that the error is in the first line?
Try using try-catch to determine the line number with error.

try {
if (app.activeDocument.mode == DocumentMode.INDEXEDCOLOR)  
 {  
  // blah blah  
 }  
}
catch (e) { alert("Line: " + e.line + "\n\n" +e); }

Running your script with the try/catch which works. I added two lines, the last of which falls over.

Running Win 7 Photoshop CC 2017.10  20170309.r.207 x 64 I get this:

try {  
if (app.activeDocument.mode == DocumentMode.INDEXEDCOLOR)    
 {    
  // blah blah    
 }    
}  
catch (e) { alert("Line: " + e.line + "\n\n" +e); }  
var m = app.activeDocument.mode;
if (m == DocumentMode.GREYSCALE) alert("Grey"); // error 1320 Invalid enumeration value

It'd be more apropriate you marked that as correct solution, as that's what you wanted: Multiple point selection in code
