Hi:
I am writing rap program with remoteobject. inthe server side remoteobject I want to call a method defined in the client remoteobject. I tried to use call(method,properties), but nothing happened. I really need the immediate results in the server side remoteobject. so I do not want to implement it by notification.
could anyone help me?
regards!

Hi,
in your client typeHandler you have to define all available methods that
will be called by the server:
------
rap.registerTypeHandler( "my.customWidgetType", {
....
methods : [ "callMe" ]
} );
------
See also RAP custom widgets FAQ:
https://wiki.eclipse.org/RAP/Custom_Widgets_FAQ

HTH,
Ivan

Hi,
it's like in your example:
remoteObject.call( "methodName", properties );
..... and in your typeHandler you have:
"methods" : [ "methodName" ]
The function "methodName" is actually implemented in your JavaScript
custom widget object.
Do you see your method called in the protocol JSON message?
HTH,
Ivan

no,I can get nothing at all. I defined a method as:
methodname: function(){
//do something
}
is that right? or how should I define the methods in the Javascript?

Yes... that's correct.
Could you attach your custom widget source code... or part of it
responsible for method call? Please look at HTTP response when you call
the method from the server-side. Do you see a JSON call operation in the
protocol message? A fragment like:

|["call","w13","myMethod",{}]|

Best,
Ivan

okay.
in the client side:
rap.registerTypehandler("demo.customwidget",{
......
methods: ["testcall"]

......
});

demo.customwidget.prototype={
testcall : function(){
//do something
}
......
in the server side:

remoteobject.call("testcall",null);

at the same time, I want to get a string alike result from the call. could the remoteobject call make it?

Hi,
your code looks good. If there is no call operation in response JSON
message your remoteObject.call is not invoked. Without a complete widget
code I can't help you much.
Best,
Ivan
