Problem with command type in Selenium session

Hi,

I am having problems with 'type' command in Selenium session. I am trying to enter some value into input field in my web application. Command performs successfully but the value is not entered into input field.

I assume that the problem is in input field because it has some 'onkeyup' action that checks the inserted value.

The 'onkeyup' action is this:

onkeyup="PrimeFaces.bcn(this,event,[function(event){bindSipOrMagcfProperties(this)},function(event){PrimeFaces.ab({s:"form-subscriber:summary-tgrp",e:"keyup",p:"form-subscriber:summary-tgrp",u:"form-subscriber:agcf-sip_subscriber"});}])"

Has anybody come across some similar situation? How can I insert my text into this input field?

I am using iTest 5.1. I am also using Chrome browser (latest version). Unfortunately I can not use Firefox or IE browser because my web app supports only Chrome browser.

Is there maybe a way to disable this 'onkeyup' action and then enable it again after text insertion?

Thank you very much.

Regards,

Ales
