I'm sure you want to achieve something else with your implementation. At
the moment you send a request AND clear the textfield with every
keypress of the user. How should the user insert any text if you clear
away each character he types? Additionally sending every inserted
character with a single request will for sure drive your server crazy.
In general it is always better to listen to specific events (like
pressing the "enter" key) rather than react on generic events (in your
case: every keypress).
--snip--
_onSendMyMessage: function(e)
{
// e is the event object -> key event instance
if (e.getKeyIdentifier() == "Enter")
{
var reqKirimPesan = new qx.io.remote.Request("JtChat/post.php",
"POST", "text/plain");
// you do not need to use this method -> it uses a form
submit instead of XmlHttp
//reqKirimPesan.setFormField("message",
this._mytextfield.getComputedValue());
// add data to the request
reqKirimPesan.setData(this._mytextfield.getComputedValue());
reqKirimPesan.send();
// clear the textfield
this._mytextfield.setValue("");
}
}
--snip--
This implementation should also work in Opera.

What does not work? As I mentioned in the example above use "setData"
instead of "setFormField" at the request object. The latter method uses
a form submit internally which is for sure not what you intend to use.
