I understand your concern. In retrospect the try/catch blocks,
specifically in handleTransactionResponse(), could be removed in the
debug version so errors/exceptions thrown in the callback aren't
"caught". In the meantime, please feel free to remove it[the
try/catch blocks] for testing and debugging.
The try/catch was necessary to prevent FF from throwing infinite
errors when JS errors are encountered in the callback; it appears the
transaction becomes reentrant. Insofar as I have tested, IE, Opera,
Safari have not exhibit this behavior. Hopefully, I will have a more
discrete solution to supersede the current logic at some point.
