Rami,
I've been trying to reproduce the stack trace you saw. (Note: we always like a
test case so we can be assured we really fix something when we make a change).

In this one, you say you've installed an lzo in lps/components. Here's what I
have:
LPP-10066-lzo.lzx:
<library>
<class name="class1">
<view bgcolor="0xFF33AA" width="200" height="50" />
</class>
</library>
LPP-10066.lzx:
<!-- -->
<canvas>
<include href="LPP-10066-installed-lzo.lzx"/>
<simplelayout axis="y" spacing="10"/>
<class1/>
<class1/>
</canvas>
How to compile/run:
cd $LPS_HOME/test # this is where my source files are
rm -f $LPS_HOME/lps/components/LPP-10066*.lzo
lzc -c --runtime=swf10,dhtml --dir $LPS_HOME/lps/components ./LPP-10066-lzo.lzx
ls -l $LPS_HOME/lps/components/LPP-10066-lzo.lzo
# I rename it, to make sure the compiler really finds the installed file
# (I tested it the other way, without renaming, too).
mv $LPS_HOME/lps/components/LPP-10066-lzo.lzo
$LPS_HOME/lps/components/LPP-10066-installed-lzo.lzo
lzc --runtime=swf10 --output LPP-10066.swf ./LPP-10066.lzx
I get no errors in compilation, I can load LPP-10066.lzx successfully, I can
modify the library file and build it and 'install' it (rename it as above) and
see the changes I made.
Do you have any ideas how to trigger the error you saw?
(This JIRA is being tracked as http://jira.openlaszlo.org/jira/browse/LPP-10066
-- you can respond there, or just reply to this message)
Thanks!
