    "Object reference not set to an instance of an object." for 1 website.

    Hello,

    I've got multiple websites running in 1 Umbraco installation, but one of the websites isn't working. You can find the error I'm getting here: http://pastebin.com/RXzp495i.

    Does anyone know what could cause this problem? The other websites work fine.

    Jeroen

    Hi Jeroen,

    It's falling over on a recursive field (think it's called "script" - but not 100% on that).

    Taking a quick look at the source for "umbraco.presentation.templateControls.ItemRenderer.GetFieldContents", following the logic, there are a couple of things going on.  It gets the node Id (either from the Item tag/control or "pageID" set internally), then tries to get the content/property from the cache. Failing that it tries to get from the database, which if throws an exception, will try to get from the XML cache. (Which appears to be throwing it's own exception!)

    My complete guess is that you are specifying a value for the "NodeId" attribute of <umbraco:Item> for a node that doesn't exist.

    Cheers, Lee.

    Thanks Lee! Indeed it was the the "NodeId" attribute of <umbraco:Item> for that pointed to a node that doesn't exist. Changed that and everything is working again.
