Stefan:
I think Scott is right. You can't next quotation marks like brackets.
So, I see three ways to solve your problem:
1.) You can use the single quotation marks:
value="$!data.getRequest().getSession().getAttribute('formula')"
2.) You can escape the nested quotation marks:
value="$!data.getRequest().getSession().getAttribute(\"formula\")"
3.) You can evaluate this expression in advance:
#set ( $value =
$!data.getRequest().getSession().getAttribute("formula") )
value="$value"
I hope this works. I have to admit that I tested none of these three
solutions.
good luck

The reason you see it like that is because
$data.getRequest().getSession().getAttribute("formula") is returning null or
is an invalid statement. The value that is placed in the <input> tag's
"value" attribute is literally:
value="$data.getRequest().getSession().getAttribute("formula")"
This causes the form field to display incorrectly because of invalidly
nested double quotes ("). If you view the source you will see the <input>
tag in its entirety:
<input type="text"
value="$data.getRequest().getSession().getAttribute("formula")">
Also, you can clean this code up by directly accessing the HttpSession
object through RunData without accessing the HttpRequest first.
$data.getSession() or in a more velocity-correct manner $data.Session
