[Laszlo-dev] DeclareEvent event values not getting inherited

[Henry Minsky]

My mistake --- the code I was merging from SWF was explicitly nulling these
fields out later in the file.

I made a note on the WIKI at
http://wiki.openlaszlo.org/DHTML_Laszlo#Developer_Notes_for_Legals
We ought to make a slightly less terse list of gotchas for merging LFC code.
Everyone, if you get
screwed on somethng while merging, please add a note to the above list.
