Description

The controls + spring integration sample works, but only the first time the JSP is run in a single HttpSession. Looks like a Control is being added with the same name into the same control context.

Not sure it's worth fixing for 1.0, but will take a look at it.

Repro:
1) build / run the controls-spring sample
2) view http://localhost:8080/springControls/familyTree.jsp
3) refresh the page

The result is this stack trace:
