I've found a few things that are causing problems. Legals doesn't
support audio, yet, so inclusion of mp3 resources and calls to
playSound need to be removed. The stack trace happens on the
inclusion of mp3 resources... This is filed as LPP-3340 http://
www.openlaszlo.org/jira/browse/LPP-3340
Commenting out the mp3 resources gets us further, and each of the
calls to LzAudio.playSound need to be commented out.
Next I found some issues in basecrollbar, a bunch of places where the
code was accessing this.thumb without checking whether this.thumb
exists. This is the don't-dereference-a-null-pointer problem; swf
silently fails when you try to dereference a null pointer, but dhtml
gives up. I've just patched lps/base/basecrollbar.lzx, and I'll go
through the file-a-bug, suggest-a-patch process. Give me a couple of
days, and I'll have a fix checked in for that.
With those changes, we compile ok, and get as far as loading the
splash. Then... the constraint on the "latLbl" button refers to
orLbl, but orLbl is null; i think you meant vflds.orLbl but for
simplicity and for now, i took out the constraint on y completely.
Same for the longitude label, each time orLbl and latLbl appear in
the code.
And now I get as far as an error at startup on "Amsterdam is not
defined". I can kind of see where that's going; "Amsterdam" needs to
be interpreted as a string literal, not a javascript identifier. I'll
try to isolate this. Can I test this usefully without running the cgi-
bin's on my machine?
Hope this helps; I'll try to look at it again, and send real diffs.
Given that it already pointed out a bug in one of the base
components, it seems like a very useful exercise :)

PT & Benjamin,
The app I am trying port to DHTML runs at topoblog.com. The source
is in subversion at: https://svn.sourceforge.net/svnroot/topoblog.
All I have done with legals so far is to put my source in
\openlaszlo-4x\Server\lps-4.0.x\topoblog and try compiling my main
file (topoblog.lzx) using the three available targets (swf7, swf8
and dhtml). The dhtml target generates the stack trace previously
supplied, while the other two at least compile (although there are
evident porting changes that need to be made under those two
targets - as expected).
Based on what I have read thus far, I do have embedded fonts (which
I don't think should cause a compile stack trace), and I probably
do have poorly handled null pointers (there do seem to be
indications that this could cause a compilation problem). So I
will look at the null pointer situation first and let you know of
my success.
Thanks for your help!

James, this looks like a bug in the compiler. If you could give
details on exactly what you did to provoke it, it would help us track
the bug down.
In general, you should _not_ expect to have to change your
application a great deal to port to Legal's. There is some
information on incompatibilities here:
http://wiki.openlaszlo.org/Runtime_Differences
and Ben has written up his experience porting one of the larger demos
here:
