Extension interoperability not working in server AS

Hi,
I tried any way to communicate with another extension in server side AS, but I always get the same error:
----------------------------------------------------------
[MainExt.as]: extension found? it.gotoandplay.smartfoxserver.extensions.Javascri
ptExtension@1e85adf

As you can see from the first line, I can successfully locate the other extension, and it gets traced. Also, I try to trace the method, and it successfully locates it. BUT whenever I try to call the same method (that just traced successfully) it never works.

thanks

Please show us the snippet of code that was used to trace out those tests.

Sure here it is,
it's part of a OOP-like fraework implemented in server side js, so it may not be too clear... anyway all extension inherit from this.

Code: Select all

System.prototype.callExtension				= function(extName, method, par) {
	trace								("calling extension: "+extName+"."+method+"() " + this._zone);
	
	this._ext							= this._zone.getExtension(extName);
	trace								("extension found? "+this._ext);
	trace								("Does it have a method? " + this._ext.handleInternalRequest);
	trace								("Letrs call it: "+this._ext.handleInternalRequest());
	if (par)							return this._ext.handleInternalRequest(par);
	else								return this._ext.handleInternalRequest();
}

It's supposed to call a custom method in the desired extension, but since it wasn't working I tried calling handleInternalRequest() directly.

If you look at the trace statements,
the first 2 are traced (extension, and method found), the third, which invokes the method, doesnt execute and triggers an error.

thanks a lot!

It seems that the exception is occurring on the following line:

trace("Letrs call it: "+this._ext.handleInternalRequest());

So perhaps it's complaining because you're not passing any parameters to the method.
