The structure of a Laszlo application is that the runtime LFC library is compiled entirely by the script compiler, it is just a big action block.

Then, the user's application is also compiled by the script compiler into a big action block.

Then those are inserted into a kind of boilerplate framework which is generated using the old JGenerator library which we've modified somewhat. That is generated by the source code in WEB-INF/lps/server/src/org/openlaszlo/compiler/, and consists of various resources and trampolines into the LFC, such as buttons for catching click events, keyboard events, and a video object which can be attached to play video.

The question I have is whether the bad opcode is coming from our script compiler, or whether it comes in somehow when the app is assembled by placing the compiled script code into the application framework.

mmm.. not sure I understand this layout. The problem is with the "runtime"
of openlaszlo itself, so assuming this library is compiled itself with
openlaszlo the goal is to have the compiler compile the smallest SWF possible.
I mean, I don't need to import my own SWF, rather I need openlaszlo to produce
a *small* file, the simplest possible. Possibly proceeding incrementally by
compiling some of the primitives in the library as a second step.
