For the currently released version of OL (4.6), if you download the
Flash debug player, you will at least get a pop-up notification,
rather than a silent failure. You can download the debug player here:

We've just added a feature in trunk to make swf9/10, when compiled in
debug mode, catch and report these errors. We've also added
backtracing to the swf9/10 platform. See:
http://jira.openlaszlo.org/jira/browse/LPP-8479
This feature will be available in tomorrow's trunk-nightly build, and
in the 4.7 release.

Hi,
I experimented a couple situations where swf9 code silently fails.
The first
one is the one Rami reported.
If you try to call a method without args, but it declares some args,
execution silently fails too.
Same result if you try to do: var x = doSomething() where
"doSomething" is a
void method.
I wonder if the swf9 architecture can catch these errors in order to
display
a laszlo error.

That's correct. Constraints will only work properly with OL
attributes.
Things like array.length don't tell the runtime when they change,
so the
constraint doesn't know when to update...

It probably has something to do with the dependencies...
Maybe my code is incorrect when it refers to
"parent.someArr.length" in
the constraint?
Am I allowed only to refer to attribute names of laszlo nodes in
constraints?
So that dependencies can be constructed properly.

Hi,
I stumbled upon a problem with swf9 (and up) attribute constraints.
Here is sample code that works in swf8 but fails silently in swf9
<!-- The problem is with setting of bgcolor attribute -->
<canvas debug="true">
<view name="test">
<attribute name="someArr" value=" new Array()"/>
<view width="100" height="100"
bgcolor="${parent.someArr.length == 0 ? 'red' : 'blue'}" x="30"
y="45">
<handler name="oninit">
Debug.inspect(parent.someArr.length == 0)
</handler>
</view>
</view>
</canvas>
Here the same thing slightly modified so that it works in swf9
<!-- The problem is with setting of bgcolor attribute -->
<canvas debug="true">
<view name="test">
<attribute name="someArr" value=" new Array()"/>
<view width="100" height="100" bgcolor="$
{this.hasErrors() ?
'red' : 'blue'}" x="30" y="45">
<handler name="oninit">
Debug.inspect(parent.someArr.length == 0)
</handler>
<method name="hasErrors">
return parent.someArr.length == 0;
</method>
</view>
</view>
</canvas>
So it seems to me that something gets screwed parsing attribute
constraints in swf9.
Any ideas?
