Hi Roman,i am using Safari on Mac OS X 10.5.6. Safar has a good Developement Konsole but in this case i got no Error there. Thank you for the hint with the "this." in front of the login Button, i really forgot this. I don't know how i could oversee this.

Hi TomWell, you're actually assigning the listener to a invalid variable. You never assigned a value to "this.loginButton". You should set it in youraddContent method, like this: this.loginButton = new qx.ui.form.Button("Login"); Note the "this." in front of "loginButton" :) What kind of development/testing environment do you use? I think you should have gotten some error messages in your logs? I strongly recommend you to use Firefox/Firebug.. helps a lot in JS development. Cheers - Roman Thomas Schober wrote:Hi Roman,thanks for the help. But the listener is still not executed. I tried the things you described already (without adding the third parameter ,this).But that did not help. Do you have any other tipps ? When i click the button nothing happens. Regards -Tom Am 18.01.2009 um 17:19 schrieb Roman Schmid:HiYou should always add the listener as reference to the function, likethis: this.loginListener NOT: this.loginListener() the second example will actually call the function and return the functions return value which is clearly not what you want.Other than that, i advise you to bind the function to "this" (to makesure, the function execution takes place in the right context). Like: this.loginButton.addListener("execute", this.loginListener, this); Notice the third parameter here.

But the registered listener is not called, when i press the button. Nothing happens ? Is it not allowed to hand over a function pointer from another class as listener ?
