What you are seeing is an uncaught error in the runtime that is being
handled by the last resort error handler. The line number refers to
the compiled LFC. If you inspect that file at that line, you can
search back for a comment of the form:
/* -*- file: data/LzDatapointer.lzs#268.27 -*- */
which will give you the source file. Hm. That is not right. I
looks like these comments are being dropped in some cases. http://
jira.openlaszlo.org/jira/browse/LPP-4298
But poking around in the sources I can see that your error is
occurring in LzDatapath's destroy method:
@@ -381,7 +387,8 @@
//if immediate parent was deleted, don't worry about the
datpaths dependent

//need to assign __LZdepChildren to parent
var dnpar = this.immediateparent.searchParents
( "datapath" ).

Thanks for that. I just applied the change in 4299 (to
LFCdhtml-debug.js, LFCdhtml-profile.js, and LFCdhtml.js), but that
doesn't seem to have fixed the error. I'm still seeing the same
message.
