I believe 'this' is the context from where the handler is called.
Unfortunately, there is no parameter in rpc.callAsync to pass the context.
You can, however, use qx.lang.Function.bind() to "force" the handler to the
right context:
rpc.callAsync(
qx.lang.Function.bind(this.__yourHandlerDefinedInThisClassFile, this),
'yourRemoteMethod', yourParameters);
Does that help?
Cheers,
Fritz
