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