If you add the following line to the beginning of your script, you'll
see that the view in question is not yet initialized:
Debug.write(bugInstance.isinited);
Although they claim that this chapter is optional reading, I've found
that in my own experience I've had to read it over and over again:
http://www.openlaszlo.org/lps-latest/docs/guide/initialization-and-instantiation.html
Generally I try to keep my code out of script blocks except for very
special cases. It's much better to have the code as methods of views,
then you are much less likely to run into these sorts of problems.
hope that helps.
