I have a slight glitch in a webpart. On the webpart, after the page loads, the first time you click on a row, this error pops up. You can navigate to a different tab on the same page or click another row or use the select all checkbox and it will no longer do this. However, if you then refresh the page, it will do it again. I have seen a few others have this issue and they had to rebuild the whole page. The webpart works fine however, and you can do whatever you want, its just annoying so I want to get rid of it. Any thoughts??!
Update: 10/13 - It seems that in some cases, rebuilding the page exactly the same way corrects the issue. This is okay for smaller pages, but it is very tedious for larger more complex pages.
