The constructor is the default constructor, which is Instance.make. The initialize method is called by the constructor as the last thing before it returns the new instance.

If you build the LFC for the DHTML runtime, you can look at the 'expanded' Javascript, which approximates what is compiled down to SWF.

  buildlfc --runtime=dhtml ...

That might make it easier to understand the class declarations.

I've found at least *one* of the nogo points.

Commenting out this line:

LzLoadQueue.timeoutDel = new LzDelegate( LzLoadQueue , "checkTimeout" );

In kernel/swf/, get successfully to my trace.

I've changed the code to:

_global.trace('initializing LzLoadQueue.timeoutDel');
LzLoadQueue.timeoutDel = new LzDelegate( LzLoadQueue , "checkTimeout" );
_global.trace('LzLoadQueue.timeoutDel (not) initialized');

The second trace is *never* reached.

Now, looking at LzDelegate class definition:


Which function is the constructor ? Is it 'initialize' ?

Found a workaround:

'_global.trace("message");' bypass the surveillance.

That looks like a 'feature' in the compiler.  It seems that it
intentionally compiles away any `trace` calls. Perhaps this was to
avoid debug output in production.

Try building your LFC with:

 buildlfc -DcompileTrace=flash ...

No difference, no even additional warnings.
Note that the trace() calls I'm adding to  .lzs files,

On top of LaszloLibrary.lzs:

trace("LaszloLibrary.lzs included");
