We are using the auto-suggestion property that Linus made

http://world.episerver.com/Blogs/Linus-Ekstrom/Dates/2012/11/Creating-a-more-advanced-property-editor/

We are using the "old" version because the site is not in 4.5 yet and we have problem with two things.

1: If you accidently click in the textbox (or type something and erase it) we got a error message saying that a value must be entered even that the property is not requierd

2: If you type something in it and the wait a little while or click outside the textbox there are a javascript error saying:

_30e {stack: "Error: Request canceled↵    at Error (native)↵    …97/ClientResources/epi/shell/widgets.js:2:333598)", message: "Request canceled", response: Object, status: undefined, responseText: undefined…}
