From what I see in my errorlogs, the on("error") code executes in the datasession in which the error happened, and it's a global handler object just like the one you have.

Not sure, but maybe the debugger knows. I know it shows datasessions switching as the code executes, but if in the call stack you go a few levels back, it should show all the variables and fields as they were... so maybe it switches the DS maybe not. Don't have a ready example at hand, and am too fuzzy with flu to build one - and you seem to have one at hand, so just add a watch on SET("Datasession") in your debugger and see whether it works.
