This was requested by a conference attendee.  Best to describe the Use Case first.  Imagine someone is embedding BIRT into a web application. 
 - They are going to write their own Ajax viewer framework.  
 - They want the reports to show up as a <div> within their larger app.  
 - Their users can build reports using report designer
 - Their users want hyper-links within the report
 - They don't want to refresh the URL for the whole page when a user follows a report hyper-link.  They just want to refresh the report div.
 - The hyperlink built in the UI uses a URL, which refreshes the whole page, which they don't want
 - They want a UI page where the user can define a call to a JavaScript function, which they will write.  The javascript function will handle the refresh of the div with new report content.
 - UI components include:
    - a text box to name the javascript function
    - a appendable list of two part controls where part one is a name of the parameter and part two is an expression builder for the value of the parameter.


I realize that this same effect can be achieved now using script or the text control, the problem is that the report designer is left having to write the script, which may be beyond their skill level.  Using a 'friendly' UI isolates the report designer from having to generate client side javascript.
