[Laszlo-user] Catching errors on resource loading

[Jason Stafford]

There is an "onerror" handler that you can define in the view that is 
waiting for the "onload" event, but in your case I think it may be that 
OpenLaszlo or Tomcat doesn't like the formatting of the error message 
that your servlet generated.  I think you need to make sure your error 
return is valid html or something. 

Sorry I can't be more helpful, but I'm just starting this phase of my 
own OpenLaszlo project myself.
