addFramework throws Cannot read property 'children' of null error

[ldeluca]

I am using the simple example from the xcode npm module readme file:

var xcode = require('xcode'),
            fs = require('fs'),
            projectPath = 'test.xcodeproj/project.pbxproj',
            myProj = xcode.project(projectPath);

        // parsing is async, in a different process
        myProj.parse(function (err) {
            //myProj.addHeaderFile('foo.h');
            //myProj.addSourceFile('foo.m');
                var path2files = "test.framework";
            myProj.addFramework(path2files);

            fs.writeFileSync(projectPath, myProj.writeSync());
            console.log('new project written');
        });

If I comment out .addFramework I get the 'new project written' message. but if i leave it in I get an error. The file is in the same location where i'm running my npm module from. I tried playing with the path variable (which is why it's a var) but no luck.

error:

pluginsGroup.children.push(pbxGroupChild(file));

To workaround, create a group named "Frameworks".
