[Laszlo-user] how do I find out which object is undefined?

[Marc Bachstein]

Hello,

I have also posted into the forum:
http://forum.openlaszlo.org/showthread.php?t=12099

I am using OL release 4.1.1, proxied="true", lzr=swf8 and I am using the swf
compiled by lzc.

For debugging I use the OpenLaszlo Debugger.

After I push a button in the application a few methods become executed
containing also an image request to the server backend. The image however
does not become displayed and the OL Debugger contains the message

[object Object]
undefined

After this the application as well as the OL debugger cannot be applied any
more.

Now I wanted to find out which object is undefined and was asking for a
method to do this.

I have tried IE 7 and Firefox 2. In both browsers the application fails in
swf8 runtime. In dhtml runtime the application works well. When I start the
application with the lzx compiled by the server the problem also does not
occur in swf8 (both browsers). 

@ Geoff Crawford : How do I set breakpoints in Laszlo source code?

Kind Regards,
Marc
