I am currently developing an InDesign CS6 Extension using Adobe Flash Builder 4.6. Suddenly, my previously functioning code has started throwing the error null is not an object. The issue seems to be in a JavaScript injection (last line):
public class Script {
private static var _instance:Script;
[ Embed (source="script.jsx", mimeType="application/octet-stream") ]
private var ScriptClass:Class;
private var jsxInterface:HostObject;
public function Script() {
if (Script._instance) {
throw new Error("only single instance allowed");
}
Script._instance = this;
this.init();
}
public static function getInstance():Script {
return _instance;
}
private function init():void {
Log.log("HostObject.mainExtension: "+HostObject.mainExtension);
for each (var s:String in HostObject.extensions) {
Log.log("Extension: "+s);
}
this.jsxInterface = HostObject.getRoot(HostObject.mainExtension);
this.jsxInterface.eval(new ScriptClass().toString());
}
public function getScript(name:String):Object {
return this.jsxInterface[name];
}
public function exec(name:String, args:Array = null):Object {
return InDesign.app.doScript(
this.jsxInterface[name], ScriptLanguage.javascript, args, UndoModes.AUTO_UNDO); // <-- this is where the error appears
}
I have checked all arguments of InDesign.app.doScript for null values, but everything seems to be correct. This is the function being called inside script.jsx:
function prepareForImageExport(params) {
var pageItem = params[0];
var prefix = params[1];
var bounds = params[2];
var ax = params[3];
var ay = params[4];
// Code continues...
}
I am currently at a loss as to where the error is occurring within the JavaScript code.
Being new to ActionScript, I am struggling to find documentation on debugging JavaScript injections in ActionScript. Additionally, I am unsure about which variables (such as app) are accessible within the JavaScript code and which ones (like console - I can't use console.log) are not.
Any assistance or guidance on this matter would be highly appreciated!
