How can I support window.external.xxx in cef framework

I want to switch from an embedded IE activeX to the libcef framework. My web project's javascript call C++ function use window.external.xxx method. But I can't get window.external object in cef framework. I try to bind my c++ function in window object. sadly, it doesn't work for me.
My code for binding c++ function to window object is like that:
CefRefPtr<CefV8Value> ptrGlobalObj = context->GetGlobal();
CefRefPtr<CefV8Value> jsCallOrthoLink = CefV8Value::CreateFunction(_T("CallOrthoLink"), m_ptrV8Handler);
ptrGlobalObj->SetValue(_T("CallOrthoLink"), jsCallOrthoLink, V8_PROPERTY_ATTRIBUTE_NONE);
I test it with window.xxx method in javascript. it works. so I know my bind codes are correctly.
How can I fixed this issue with window.external.xxxx method?

Try this:
external = CefV8Value::CreateObject(NULL, NULL)
external->SetValue("CallOrthoLink", jsCallOrthoLink, V8_PROPERTY_ATTRIBUTE_NONE)
global->SetValue("external", external, V8_PROPERTY_ATTRIBUTE_NONE)

Calling Java function from Rhino

Calling Javascript functions running inside Rhino from Java is easy enough - that after all is why Rhino was created. The thing I am having trouble establishing is this:
Context: I have a Phonegap CLI (v 6.3.3) Android project (API 19+) where I do a great deal of processing via loadable JavaScript running inside rhino
A Phonegap plugin - which I am creating at the same time as the actual Phonegap app - contains class called Storage which provides public, static, methods such as readFromFile(String fileName), writeToFile(String fileName,String data) etc.
What I want to be able to do is to call Storage.readFromFile etc from my loaded JavaScript code in Rhino.
Just how this should be done is not too clear to me. From the searches I have done thus far it involves using ScriptableObject.putProperty to pass the Java class in question, Storage in my case to JavaScript. However, how this should be done and then how it should be used at the JS end leaves me rather confused.
I would be most grateful to anyone here who might be able to point me in the right direction

Given that Rhino has less than 100 followers here it should perhaps come as little surprise that this question was not answered. In the mean time I have managed to find the solution myself and it turns out to be very simple. I share it below for the benefit of anyone else running into this thread.
My Storage class is very simple. It goes something like this
public class Storage
{
public static boolean haveFile(){}
public static boolean readFromFile(String fname){}
...
}
When I call Javascript from Java via Rhino I simply pass a new instance of the Storage class as the last of my function parameters
Context rhino = Context.enter();
Object[] functionParams = new Object[] {"Other parameters",new Storage()};
rhino.setOptimizationLevel(-1);
try
{
Scriptable scope = rhino.initStandardObjects();
String rhinoLog = "var log = Packages.io.vec.ScriptAPI.log;";
String code = /*Javascript code here* as shown separately below/;
rhino.evaluateString(scope, rhinoLog + code, "ScriptAPI", 1, null);
Function function = (Function) scope.get("jsFunction", scope);
Object jsResult = function.call(rhino,scope,scope,functionParams);
}
where the Javascript code is
function jsFunction(a,s)
{
//a - or a,b,c etc - here will be the "other" parameters
//s - will be the instance of the Java side Storage class passed above
//now you can do things like
s.writeToFile('fileName','fileData');
var fd = s.readFromFile('fileName');
s.dropFile('fileName');
...
}

OnContextCreated() in Cef not being called

I have a similar problem to the person in this post; I'm trying to extend the cefsimple.exe app included with the chromium embedded framework binaries to include a V8 handler. I implemented the OnContextCreated() method and made sure to extend RenderProcessHandler in the SimpleHandler class. I'm trying to implement a simple window bound variable called test_string; here's what my code looks like;
void SimpleHandler::OnContextCreated(
CefRefPtr<CefBrowser> browser,
CefRefPtr<CefFrame> frame,
CefRefPtr<CefV8Context> context)
{
CefRefPtr<CefV8Value> object = context->GetGlobal();
object->SetValue("test_string", CefV8Value::CreateString("this is a test"), V8_PROPERTY_ATTRIBUTE_NONE);
}
But the program never arrives at any breakpoints I add within the method, and the variable is undefined on any webpages I load within the app. I saw that one of the solutions in the other thread is to enable the settings.single_process flag, which i've done, but my code still doesn't reach the breakpoint.
To be clear, I'm accessing the variable on pages with window.test_string.

Make sure that you are sending that CefApp to CefExecuteProcess.
CefRefPtr<SimpleApp> app(new SimpleApp);
// CEF applications have multiple sub-processes (render, plugin, GPU, etc)
// that share the same executable. This function checks the command-line and,
// if this is a sub-process, executes the appropriate logic.
int exit_code = CefExecuteProcess(main_args, app, sandbox_info);
if (exit_code >= 0) {
// The sub-process has completed so return here.
return exit_code;
}
Found this solution here

Have you read through the General Usage guide? Some key points below
https://bitbucket.org/chromiumembedded/cef/wiki/GeneralUsage#markdown-header-cefapp
https://bitbucket.org/chromiumembedded/cef/wiki/GeneralUsage#markdown-header-processes
The single_process mode is not supported so I've never used it. In general I'd avoid it. The multi process architecture means you need to attach the debugger to the process. The Chromium guide is relevant to CEF in this instance.
https://www.chromium.org/developers/how-tos/debugging-on-windows#TOC-Attaching-to-the-renderer

you need to ensure your App is derived from CefRenderProcessHandler
not SimpleHandler!!!
class SimpleApp : public CefApp
, public CefRenderProcessHandler
{
virtual void OnContextCreated(CefRefPtr<CefBrowser> browser,
CefRefPtr<CefFrame> frame,
CefRefPtr<CefV8Context> context) OVERRIDE;
valdemar-rudolfovich says you need to pass instance of SimpleApp in
CefExecuteProcess

Using a .NET DLL in JAVA SCRIPT - Registered through REGASM

I have registered a .NET DLL using REGASM and registration is successful. I'm able to create object of the classes and use them in my Javascript. The class I consume i sa non static one.
This is how I'm using and it is working,
var objDP = new ActiveXObject("PE.Core.PacketExtractor");
objDP.PrintMessage();
objDP.Start();
My problem :
I have a methods in my C# class which I would like to call and get the value. The method signature is given below,
Signature : Get_Current_Faults(ref PEFaults my_faults);
Usage : Get_Current_Faults(my_faults);
In this method the "PEFaults" is a public C# Struct. This is also COM Visible and registered as I could see an entry in the Registry.
I tried to get data in JavaScript by doing the following,
var objFault = new ActiveXObject("PE.Core.PE_FAULTS");
objDP.Get_Current_Faults(ref objFault);
WScript.echo(objFault.Temperature);
But this is not working and giving an error "Automation Server cant create an object" # PE.Core.CURRENT_FAULTS object creation.
Cant we create an object of Struct in JS ? Any idea how to handle a ref parameter ? How else I can make this work ?
Please advise me. Thanks.

How can i set field mandatory to false using javascript

I am new to netsuite scripting using javascript. I like to ask, how can I set field mandatory to false using javascript.
Hope that someone can help me.

Note :
If you use nlapiGetField(fieldname) in a client script to return a nlobjField object, the object returned is read-only. This means that you can use nlobjField getter methods on the object, however, you cannot use nlobjField setter methods to set field properties.
However you can use
nlapiSubmitRecord(item_obj, true, true); to ignore mandatory fields on a record.
For more details check out the included parameters in the method.
nlapiSubmitRecord(record, doSourcing, ignoreMandatoryFields);

You are using the correct methods, but setMandatory is not supported in a client script. You can instead try using the exact same code in a User Event, Before Load event handler.
Contrary to the documentation, the nlobjField returned by nlapiGetField is not read-only. Some of the setter methods still work (e.g. setDisplayType) on the client side. You can experiment with which ones do and do not work, but setMandatory is confirmed as not supported on the client side.

Using SS2.0 on a client script you can make it mandatory with this code:
var newSupervisorField = context.currentRecord.getField('custrecord_new_supervisor');
newSupervisorField.isMandatory = true;

This is what worked for me based on the input from #erictgrubaugh and #user3627301
function fieldChanged(type,name){
var metodPayment=nlapiGetFieldText('field_id_to_check');
if ((name == 'field_id_to_monitor_for_change') && (metodPayment=='Financing')) {
var field1 = nlapiGetField('field_id_to_be_disabled');
field1.setDisplayType('disabled');
}
}

You can set mandatory using SuiteScript 2.0 though although it does not works in 1.0.
Below, is an example snippet using client script on customer record
var currentRecord;require(['N/currentRecord'], (currentRecord) => {
var field = currentRecord.get().getField('comments');
field.isMandatory = true;
})

Maybe my answer was already late but for others that came across this post, this is how I do it via client script.
nlapiSetFieldMandatory('yourFieldId', true);
This was already tested because I am using this often. Though some says you cannot set fields to mandatory via client but you can. I did not find any docs about this on netsuite docs though.
