Iterate over intergertype property

I'm reading through jazz-y's excellent explanation into action manager code:

About halfway down, instead of geting the artboardRect properties I try to look at the layerKind at a bit of text. Only it's not an OBJECTTYPE, but a INTEGERTYPE - so I should be able to loop through it?

var q = " - ";
var prop = "layerKind"; // layerKind - DescValueType.INTEGERTYPE

var r = new ActionReference();
r.putEnumerated(stringIDToTypeID("layer"), stringIDToTypeID("integer"), stringIDToTypeID("targetEnum"));
var d = executeActionGet(r).getObjectValue(stringIDToTypeID(prop));

str = prop + " properties\n";
for (var i = 0; i < d.count; i++) 
{
  str += typeIDToStringID(d.getKey(i)) + q + d.getType(d.getKey(i)) + "\n";
}
alert(str);

Only, I get general error 8800 which isn't useful to tell me where I'm going wrong.

Any ideas?

I am not sure I understand the issue.

As an integer has no count the for-clause cannot work on that.

To check for Layers’ properties I use code like this

if (app.documents.length > 0) {
var ref = new ActionReference();
ref.putEnumerated( charIDToTypeID("Lyr "), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") ); 
var layerDesc = executeActionGet(ref);
checkDesc2 (layerDesc);
////// based on code by michael l hale //////
function checkDesc2 (theDesc) {
var c = theDesc.count;
var str = '';
for(var i=0;i<c;i++){ //enumerate descriptor's keys
	str = str + 'Key '+i+' = '+typeIDToStringID(theDesc.getKey(i))+': '+theDesc.getType(theDesc.getKey(i))+'\n'+getValues (theDesc, i)+'\n';
	};
alert("desc\n\n"+str);
};
////// check //////
function getValues (theDesc, theNumber) {
switch (theDesc.getType(theDesc.getKey(theNumber))) {
case DescValueType.ALIASTYPE:
return theDesc.getPath(theDesc.getKey(theNumber));
break;
case DescValueType.BOOLEANTYPE:
return theDesc.getBoolean(theDesc.getKey(theNumber));
break;
case DescValueType.CLASSTYPE:
return theDesc.getClass(theDesc.getKey(theNumber));
break;
case DescValueType.DOUBLETYPE:
return theDesc.getDouble(theDesc.getKey(theNumber));
break;
case DescValueType.ENUMERATEDTYPE:
return (typeIDToStringID(theDesc.getEnumerationValue(theDesc.getKey(theNumber)))+"_"+typeIDToStringID(theDesc.getEnumerationType(theDesc.getKey(theNumber))));
break;
case DescValueType.INTEGERTYPE:
return theDesc.getInteger(theDesc.getKey(theNumber));
break;
case DescValueType.LISTTYPE:
return theDesc.getList(theDesc.getKey(theNumber));
break;
case DescValueType.OBJECTTYPE:
return (theDesc.getObjectValue(theDesc.getKey(theNumber))+"_"+typeIDToStringID(theDesc.getObjectType(theDesc.getKey(theNumber))));
break;
case DescValueType.RAWTYPE:
return theDesc.getReference(theDesc.getData(theNumber));
break;
case DescValueType.REFERENCETYPE:
return theDesc.getReference(theDesc.getKey(theNumber));
break;
case DescValueType.STRINGTYPE:
return theDesc.getString(theDesc.getKey(theNumber));
break;
case DescValueType.UNITDOUBLE:
return (theDesc.getUnitDoubleValue(theDesc.getKey(theNumber))+"_"+typeIDToStringID(theDesc.getUnitDoubleType(theDesc.getKey(theNumber))));
break;
default: 
break;
};
};
