Weird Error: Hitting enter key on a page leads to " does not contain handler parameter named ‘action’" error

I got a weird error about a couple of days back. My JSP page was submitting the contents of my page when I hit the enter key whilst inside the LONE textbox on the page.

I googled for the answer and found that it was probably because of the browser that was submitting the page since it found ONLY ONE TEXT ELEMENT.

So the solution:
This error was solved by simply creating another text element with “style=display:none”. The page will hence have TWO elements and so the browser wont submit the page. The user will however see only the textbox that is visible.

Here’s the weird error:

javax.servlet.ServletException: Request[/RecoverPassword] does not contain handler parameter named ‘action’.
