Custom Form Processor: How to Render Hyperlinked Object URL in Success Banner Like OOTB?

I have a custom FormProcessor that creates a new WTPart and returns a success banner message. The processor correctly generates the WTPart and its URL, but the banner message displays the URL as <a href="..."> instead of rendering it as a hyperlink.

I have tried:

• Manually constructing the URL and passing it into FeedbackMessage.
• Passing the generated WTPart inside an ObjectBean and calling super.getSuccessFeedbackMessage(objList).

Neither approach results in the OOTB hyperlink behavior seen when creating objects through standard Windchill forms. Also attached partial code. 

Is there any recommended way to return the created object so that the banner automatically hyperlinks it (similar to standard object creation)?

Any suggestions would be appreciated. Thanks.
