Hi!

Im not very familier with EPiServer 7.5 but I have done a few sites using v5 and 6.. anyway

For some reason the LinkItemCollection property-type keeps crashing the "internal" javascripts within the EpiServer page editor.

_317: Unable to load /EPiServer/cms/Stores/contentdata/10_10 status: 500 {message: "Unable to load /EPiServer/cms/Stores/contentdata/10_10 status: 500", response: Object, status: 500, responseText: "
↵
↵    
↵        ", xhr: XMLHttpRequest…}message: "Unable to load /EPiServer/cms/Stores/contentdata/10_10 status: 500"

If I expand the responseText it gives me the following exception:

Server Error in '/' Application.

This javascript error is ONLY thrown when using and populating a ListItemCollection property with a link, if I leave the property blank(Dont add any links) then all works fine.. but as soon as I add a link the editor stops working.

Is this any known problem with the LinkItemCollection in EpiServer 7.5+?
