Object not found within qooxdoo code [message #137620]

Hello everyone,

I observe a weird behavior when using the
'document.getElementById(this._id); like it is done in the GMAPs
Example. It returns null, if I don't use the two alerts (see below)
before and after this line of code. This does not make any sense to me.
How can I eliminate this error?

Furthermore this code functions within the internal browser but not
within the external (Mozilla 3.0.11).

Thanks

// get the HTML's body element
var body = document.getElementsByTagName('body')[0];

if(body) {

alert("FlashForm ContainerObject 1:"
+document.getElementById(this._id));

var ContainerObject = document.getElementById(this._id);

alert("FlashForm ContainerObject 2:"
+document.getElementById(this._id));

ContainerObject.innerHTML =
'<object width=\"425\" height=\"373\">'
+ '<param name=\"movie\"'
+ 'value=\"http://www.youtube.com/v/CwR6bFmAy-M"'
+ '"&rel=1&border=1\"></param>'
+ '<param name=\"wmode\" value=\"transparent\"></param>'
+ '<embed src=\"http://www.youtube.com/v/CwR6bFmAy-M"'
+ '"&rel=1&border=1\" type=\"application/x-shockwave-flash\"'
+ 'wmode=\"transparent\" width=\"425\" height=\"373\"></embed>
+ '</object>'
}

Hi Jessica,

instead of "document.getElementById(this._id)" use "this.getElement()".
Please not that in qooxdoo the actual HTML element is created when the
widget appears on the screen. You can move your code in the "appear" event.

Best,
Ivan
