BlackBerry BrowserField executing javascript

I tried a simple javascript [Example: document.getElementById("mydiv").style.display = "n开发者_运维百科one";] on a web page and tested it on BlackBerry 4.5 simulator browser and it worked.

Now I have an app (JRE 4.5 - Eclipse Plugin) with a BrowserField embedded in a browser and I access the same page in the BrowserField. I do have the following code added to my app

 myrenderingSession.getRenderingOptions().setProperty(RenderingOptions.CORE_OPTIONS_GUID,  RenderingOptions.JAVASCRIPT_ENABLED, true);

But the java script is not working. Do I need to add custom code to ensure java script executes? Anything in the Event.EVENT_EXECUTING_SCRIPT? Please help!

I simply can confirm I have the same code on OS 4.5 to enable JS, and the page with JS works OK for me. However should also say I don't hide anything on the page via JS, so I can't confirm if the same JS to hide an element works for me.

Also - I don't handle Event.EVENT_EXECUTING_SCRIPT in any way. So I am sure the code you are using to enable JS is enough to expect JS support in your BrowserField.
