Partial Refresh and RichFaces components on edit mode

[naspeh]

Greetings

I use Jboss Portal 2.7.2 and RichFaces 3.3.0.GA.
Partial Refresh feature is switched on.
Edit mode contain several RichFaces components.

Received javascript error on load page:
"FUNCTION_NAME is not defined"
Where FUNCTION_NAME is rich faces function name (for example ProgressBar, when used rich:progressBar component).

I know workaround: put this component on view mode and set display: none.
But it isn't good solution.

I took some investigation with javascript.
Below javascript function definition isn't working:

<script type='text/javascript'>
function test() {
alert("test");
}
</script>
<input type="button" value="Test" onclick="test()" /> // test() not found;

But when I change function definition it works:

<script type='text/javascript'>
test = function() {
alert("test");
}
</script>
<input type="button" value="Test" onclick="test()" /> // test() is called;

I think problem is in javascript evaluation. In dyna.js.
Does somebody know better solution or how we can change javascript
evaluation?

Thanks a lot.
