So when the fdb debugger runs, it prints out a bunch of things that look
like maybe verifier errors, starting with
[trace] verify <anonymous>()
[trace] exception[0] from=47 to=186 target=192 type=*
name=$lzsc$e
[trace] exception[1] from=45 to=281 target=285 type=*
name=(none)
[trace] stack:
[trace] scope: [global Object$ LzEventable$ LzNode$
LzView$ $lzc$class_LzDebugWindow$]
[trace] locals: Object * * *
[trace] 0:debugfile
"/Users/hqm/openlaszlo/lib/jakarta-tomcat-5.0.30/temp/lzswf9/Users/hqm/openlaszlo/trunk6/test/foo/build/hello;;$lzc$class_LzDebugWindow.as"
[trace] stack:
[trace] scope: [global Object$ LzEventable$ LzNode$
LzView$ $lzc$class_LzDebugWindow$]
[trace] locals: Object * * *
[trace] 3:debugline 36
[trace] stack:
[trace] scope: [global Object$ LzEventable$ LzNode$
LzView$ $lzc$class_LzDebugWindow$]
[trace] locals: Object * * *
[trace] 5:newactivation
[trace] stack: <anonymous>
The intermediate .as files made by compiling swf10 get stuck into a temp dir
in tomcat, on my machine that's
~/openlaszlo/lib/jakarta-tomcat-5.0.30/temp/lzswf9/Users/hqm/openlaszlo/trunk6/test/foo/build/hello/
for a test app test/foo/hello.lzx
The lzDebugWindow.as file shows this code block which ends at line 36 (it's
an anonymous method
on LzDebugWindow class)
function ($lzc$ignore_$1) {
/* -*- file: -*- */
var $lzsc$d_$3 = Debug;
var $lzsc$s_$4 = $lzsc$d_$3.backtraceStack;
try {
if ($lzsc$s_$4) {
var $lzsc$a_$5 = [$lzc$ignore_$1];
$lzsc$a_$5.callee = "applied='${...}'";
$lzsc$a_$5["this"] = this;
$lzsc$a_$5.filename = "debugger/debugger.lzx";
$lzsc$a_$5.lineno = 122;
$lzsc$s_$4.push($lzsc$a_$5);
if ($lzsc$s_$4.length > $lzsc$s_$4.maxDepth) {
$lzsc$d_$3.stackOverflow()
}};
with (this) {
/* -*- file: debugger/debugger.lzx#122.262 -*- */
var $lzc$newvalue_$2 = parent.default_width;
/* -*- file: -*- */
if ($lzc$newvalue_$2 !== this["applied"] || !this.inited) {
$lzsc$a_$5.lineno = 128, this.setAttribute("applied", $lzc$newvalue_$2)
}}}
catch ($lzsc$e) {
if ($lzsc$e is Error && $lzsc$e !== lz["$lzsc$thrownError"]) {
$lzsc$runtime.reportException("debugger/debugger.lzx", $lzsc$a_$5.lineno,
$lzsc$e)
} else {
throw $lzsc$e
}}
finally {
if ($lzsc$s_$4) {
$lzsc$s_$4.pop()
}}}
So I'm going to look at that and see if there's something that might be
confusing the flex compiler...
