I have exactly the same problem with the one that is mentioned in this
message from 2011
http://qooxdoo.678.n2.nabble.com/RPC-callAsync-problem-td6507653.html
The problem is that when a widget tries to make a RPC call but the
widget is disposed before the call completes, when the call finally
completes it tries to call the handler function but the context is
already disposed. I tried the solution in that message but I still have
the same problem
073267 Assertion error! Trying to call a bound function with a disposed
object as context: qssite.ui.form.widget.SimpleCountrySelect[8952-0] ::
qssite.ui.form.widget.SimpleCountrySelect.prototype.__onLoaded(): Called
assertFalse with 'true'
This is my portion of the code that makes the rpc call
var rpc = this.__rpc = new qx.io.remote.Rpc('/remote', 'qssite');
var options = {
self: this,
args: null,
attempt: true
};
this.__asyncRef = rpc.callAsync(qx.lang.Function.create(this.__onLoaded,
options), 'qssite.get_countries_list');
and in my destruct function I have
this.__rpc.abort(this.__asyncRef);
