I am also running in to this issue, for the same website, and presumably the same exercise. IE is crashing right around that chunk of my code too. I am not able to validate all of the selectors in the selector tool, but I can with some of them.
- Clicking on notification bar
- clicking on ‘save as’ arrow button
Does not validate:
- Clicking on save as popup
This is the crash I get. I believe the mention of the datatable is a red herring, because interacting with the UI of IE happens in a loop, and there is a datatable operation at the top of the loop. Since this crash started happening after I switched this part of the code from Firefox to IE, I am fairly certain that the error is actually regarding the clicks and whatnot, and NOT about the datatable.
This is the text:
Message: Cannot serialize the DataTable. DataTable name is not set.
