modify register causes exception

[panhandle76]

i created an issue that is part of the problem. a missing "import re". there is another issue with app.py, the function "register_widget_register_changed_handler" is calling self.edm_protocol_manager.procotol_ThreadContextSet(...). the function is only given one argument, but requires 3. i updated the method to pass in (pid, tid, threadContext) but still doesn't work. I tried passing self.threads[tid] as the third argument and that didn't work. i also tried calling "procotol_manager.protocol_ThreadContexGet() and then modifying the register value and passing that into protocol_ThreadContextSet() but that didn't work either. neither way caused any exceptions, but the register didn't update.
