Even without the debug player, shouldn't the LZX debugger catch the
runtime error and give at least /some/ information?
I agree with you that Sebastian must have a more subtle error that is
confusing the compiler, so it would be great if he could create a test
case.

Are you talking about compile time errors or runtime errors?
Can you give an example of a compile time error that stops the
compiler?
I tried a simple example like this with a method that the compiler
knows
does not exist at compile time:
<canvas>
<text bgcolor="#ccffcc" text="${canvas.runtime}">
<handler name="oninit">
LzView.nosuchmethod();
</handler>
</text>
</canvas>
The error reported does localize properly to the lzx file source
code line number
The application could not be compiled due to the following errors:
Compilation Errors
org.openlaszlo.sc.CompilerError: hello.lzx: 4: Error: Call to a
possibly undefined method nosuchmethod through a reference with
static type Class, in line: LzView.nosuchmethod()
It may be however that your example is doing something that confuses
the LPS compiler in a way that it is unable to parse out the flex
compiler error message and transform it back to LZX source code
filename and line numbers, so it would help to see you specific
example.
For a runtime error, like below, the compiler does not know whether
the
method exists, because 'canvas' in this example is declared as a
dynamic
variable which may have properties added at runtime:
<canvas>
<text bgcolor="#ccffcc" text="${canvas.runtime}">
<handler name="oninit">
canvas.nosuchmethod();
</handler>
</text>
</canvas>
But when it runs, it gives a runtime error in the Flash debug player.
TypeError: Error #1006: nosuchmethod is not a function.

If runtime errors, are you running with the Flash Debug player?

I think you can quite easy make a compiler issue like that cause
every time you write in your code a call to a method or attribute
that does not exist, that hole Compiler does stop and quite.

Henry and Raju have given lots of hints. I'll just add that when you
find out the cause, please file a bug if you can. Clearly we would
like this not to happen.

hi,
actually you run into a lot of compilation issues when you run a
previous application into SWF9.
I followed the SWF9 Migration Guide of course, the code has zero
problems to be compiled to SWF8.
I guess in most cases its something very tiny tricky in the code
that needs to be changed but actually you don't get anything except
*org.openlaszlo.sc.CompilerError: Errors from compiler, output file
not created*
The console does also only pring:
FAIL: compiler returned 1 ... or another number
So how do you get those Compile Errors?
I guess they are not really that handy as they will show you only
errors in the resulting ActionScript that is going to be compiled
by the Flex compiler.
So you will not see which LZX-Codeline has the error.
But without any notice at which code-block to look at its almost
impossible to migrate more then a bunch of code lines with every
compilation.
I've seen that there are some properties in the configuration:
compiler.swf9.warnings=false
compiler.swf9.execflex=true
# Tell compiler to catch errors in debug mode
compiler.catcherrors=true
changing them does seem to have an effect.
Is there a clue that is hidden somewhere or how do you judge what
needs to be done when you run into this?
thanks,
sebastian
