When pasting the TCM URI (tcm:191-371868) of a Component into the search box, we get the following message (the Core Service returns the same message):

"Specified argument was out of the range of valid values. Parameter name: itemId Unable to read Component"

The Component in question is present in the database, as I can see by the following:


FROM [Tridion_cm].[dbo].[ITEMS]
where ITEM_REFERENCE_ID = 371868


where ITEM_REFERENCE_ID = 371868

We're on 2011 SP1 HR1

  • Can you still create new Components and open them, and can you open this Component in the UI by going to its location? – Bart Koopman Jun 5 '13 at 14:08

I had this recently with an upgraded database (2009 -> 2011 SP1 -> 2013). I don't know what caused it, and because I only had a very limited use to the database, I didn't really care figuring out what it was (other than reading the component then delete the database - long story).

Anyway, it turned out to be that one of my components had a reference to a keyword that was stored in the Component's CONTENT as xlink:href="tcm:0-0-0" and this was causing the failure to read the component. Because it fails at a very low level (TOM READ), the UI can't really cope with it.

  • You should be able to see this in the DB or by trying to load the URI through the protocol handler (assuming that does still work), if you see a link to a Null URI in the content then I would suggest you contact Customer Support to get it investigated and sorted. – Bart Koopman Jun 5 '13 at 14:43
