Error In Callback

message when expanding tree in Content and Structure page in EPiServer CMS 6 Hi, We recently ran into this issue when attempting to access our site through the Content radcombobox callback error and Structure page on the main site. This error presented itself when attempting to ethere was an error in the callback expand the tree for a particular site. After clicking the plus sign and waiting for a while, the error message ajax error callback not called ("There was an error in the callback") would appear just below the site name. After receiving the error, another message appear: "Internal Server Error - Sorry, there was an internal error. Please try again
Ajax Error Callback Parameters
later". Any clues? Thanks, Lucia By: Fredrik Haglund May 18 2011, 15:31 Nope, not enough clues. You need to get a call stack and the original Exception to give us something to work with. The TreeView uses ASP.NET Callbacks with JavaScript to fetch more information and something goes wrong. Check the Event Log on the server and turn on logging (EPiServerLog.config).

Shounds like a recusive bug By: Lucia Crisan May 20 2011, 14:19 Thank you. This error seems to be relatedto this issue: http://world.episerver.com/Modules/Forum/Pages/thread.aspx?id=43734 By: Thomas Haug May 26 2011, 14:40 Did you find a solution to this? I get the exact same problem after deploying a new CMS 6 R2 site to production. The version is 6.1.379.0.There are no errors in the log nor events in the event viewer. The site is running in .NET 4 in 64-bit environment. By: Thomas Haug May 26 2011, 15:04 I resolved my problem by replacing the std web.config (with .NET4 changes) with the one from my staging server. Haven't yet figured out which config setting that does the trick. Will try to compare files and post the findings. By: nramsin August 23 2011, 9:37 Content is edited Lucia/Thomas - did you figure out the fix for this? We also have the same problem.

I have other classes that set listeners on this object and execute some stuff in a callback function. The callback function may do some error checking and use the error() function to raise an exception if there is an issue. What I was hoping for is that when this happens, that MATLAB would cease executing any remaining listeners as well as the function that triggered the event.However, from the MATLAB documentation,Callback function execution continues until the function completes. If an error occurs in a callback function, execution stops and control returns to the calling function. Then any remaining listener callback functions execute. So what I can do to get around this? Should I be using something other than an event in this case?Thanks. 0 Comments Show all comments Tags events Products No products are associated with this question.

teylyn on June 25, 2012 The other day, I had this error when I tried to point a Content by Query Web Part (CQWP) to a list on a sub site. I clicked the + sign in the tree view to open a sub site so I could see its lists, http://www.teylyn.com/sharepoint-there-was-an-error-in-the-callback-in-manage-content-and-structure/ but what I saw instead was: "There was an error in the callback." Ah! Ok. That really helped clarify the issue. Since I know my site collection structure, I decided to ignore the error and the browse button. Instead, I entered the path to the desired list manually in the field provided in the CQWP properties. Testing the CQWP I found that it works just fine. Lesson: You don't need to browse to a list if you know its URL!! But I wanted to get to the cause of the error in error. The problem apparently does not lie with actually accessing the sub site or the list by the CQWP itself, but instead with rendering the tree view to open the sub site and expose its lists. The tree view triggered by the "Browse" button when selecting site or a sub-site reminded me of the view that is presented when looking at the "Manage Content and Structure" link in the Site Collection tools (Site Actions > Site Settings). So I tried that as well. Sure enough, the site could not was an error be opened here either. After persisting a few times, I got the unloved screen informing me that "An unexpected error has occurred", followed by a correlation ID. Now, I'm an end user. I'm not blessed with access to the server logs, and don't know how to process that correlation ID. So I sent it off to our server team to find out more about it. Meanwhile, searching the mighty InterWeb, I found suggestions that either a list in the site or the site itself may have become corrupt. The best solution I found was to delete the site and start from scratch. Uhmm. No. I spent a week building the site, the lists, the content. There's got to be a better way. Then I tried this: One by one, I deleted every list in the sub-site, knowing that I could always restore them from the recycle bin. After each list deletion, I went back to the Site Collection and ran the "Manage Content and Structure" link again, testing if I still got the error. Three or four lists into the process I hit the problem piece, because after I deleted "ListX" , the error no longer showed in "Manage Content and Structure". I could now use the tree view buttons just fine. I went back to the sub-site and restored each list from the recycle bin, leaving "ListX" until last. After each restore, I ran "Manage Content and Structure" in the Site Collection. Every time it behaved just fine. No errors. Finally, I dared restore "ListX" list from the recycle bin, too. Holding my breath and starting "Manage
