Probably every Mx developer has encountered this: a page with 2 or more widgets that shows unexpected behaviour, resulting is some extensive debugging. Throw in some browser specific execution of (a.o.) JavaScript and you've got a nice puzzle on your hand. It would be great if Mendix provided some resources to streamline and improve the use of multiple widgets on a page, for example to guide business engineers towards resources such as JS Lint / JS Hint / ES Lint to check if the javascript libraries and code on more complex pages will execute as expected.
