Flex Automation: RegisterUserFunc fails

Question

Has anyone had success with registering user-defined
functions in QTP for Flex components? This is a mechanism whereby
standard method implementations are replaced with custom ones and
new methods can be added.
I've tried it with FlexTextArea, FlexButton and FlexCanvas. I
get the following dialog:
Run Error: Object doesn't support this action:
'Flex<ComponentType>(...).<Method>'
I validated my approach is with a Browser app's WebEdit.
Code:
Function MyClick
MsgBox "worked"
End Function
RegisterUserFunc "FlexButton", "Click", "MyClick", False
Browser("Runtime Loading
Sample").FlexApplication("automationExample").FlexApplication("prototype.swf").FlexButton ("releaseButton").Click

Greg,
Thanks for your help.
The "&#38;" seems to get me past that error alright.
The example was sent in an email from Adobe after I
downloaded the Flex Builder 3 Trial. I just copied and pasted it
into Flex Builder exactly as they had sent it to me.
The email message included this:
Create your first rich Internet application
Creating your first Flex rich Internet application is easy.
Just copy the following code into a new Flex project inside Adobe
Flex Builder. The application will search Flickr for photos related
to a keyword that is entered into the search box. If you have
problems, check out the Flex 3 Getting Started Guide Wiki page on
creating a simple RIA.
