A problem just started happening, I was using umbraco without issue and then for no decernable reason the content screen started giving the following error:
Exception Details: System.ArgumentException: Item has already been added. Key in dictionary: '28' Key being added: '28'
I have verified no templates have the same name and was not even working in content or anywhere else, how do I resolve this?
We keep getting this error. Touching the web.config every time is not a viable solution with an angry client on your back!
Does anyone know the cause of this? It appears to happen at the same place - I always get key 28 being returned too. What is key 28, which piece of data does it relate to and can I manipulate anything in the database to stop this happening?
I don't know the cause. I just thought I'd say that for me,it has not happened again since recycling the app pool. Probably not the answer you are looking for though :)
Not really. It happened twice yesterday, so I guess our issue has already showed signs of reoccurance.
I think key 28 is the id of first piece of content that is not a core part of Umbraco. In other words, if you removed 28, the next error would probably be on 29. :-(
Afraid not. The only crumb of comfort I can offer is that it happened a lot during a busy period of content population, where lots of people were logging into the site at the same time. Since all the content's gone in and they are only making small tweaks here and there we have had no further reports of it.
Item has already been added. Key in dictionary: '28' just started happening
Hello All,
A problem just started happening, I was using umbraco without issue and then for no decernable reason the content screen started giving the following error:
Exception Details: System.ArgumentException: Item has already been added. Key in dictionary: '28' Key being added: '28'
I have verified no templates have the same name and was not even working in content or anywhere else, how do I resolve this?
Thanks.
nevermind now it works, didn't do anything, very strange.
Got exactly the same issue (same key!) when adding parameters to a macro. Resetting the app pool fixed the issue.
Same error message, after adding some cache timings to a macro, as Arnold said, recylcing the app pool fixes the issue.
Is there a codeplex item, I'm on 4.7.0
Hello, maybe this is a redundant statement, but I had the same issue just now. Recycling the app pool worked for me too.
Not sure what caused it, was just adding nodes normally. Strange.
I'm on 4.6.2
Just keeping the thread alive... It has happend to us too - we were just editing Nodes.
Recycling the app pool worked for us too.
We are using 4.7.1.1
Does anyone know the cause of this? It appears to happen at the same place - I always get key 28 being returned too. What is key 28, which piece of data does it relate to and can I manipulate anything in the database to stop this happening?
Thanks!

Same issue here... anybody resolved it?

Based on umbraco version 4.6.X & 4.7.X , it's bug .
