Hi Eric,
I suggest you to read only the context element of 2nd line and modify the same rather re-binding whole table data back.
Also, place an EXTERNAL break point at source code where dump occurred in ST22 and try again.
Now, second time you will be able reach the break point where dump occurs. In debugging window, use the tab "STANDARD" and you can see call stack. Open the method of your component from that call stack and you would be able to figure out the point of exception and also cause for the issue.
Hope this helps you.
Regards,
Rama
