[Laszlo-dev] XML Data corruption

[Henry Minsky]

At one point there was a bug that if a null byte (value == 0) was in
the XML data, it would cause the data to become corrupted. There was a
check put into the data encoder on the LPS server, and then it was
conditionalized.


try adding this to your WEB-INF/lps/config/lps.properties file

data.removenulls = true

and restart the server.

There may also be a race condition in the loading of data, I have been
seeing some kind of race condition while debugging a test app which
loads data, but this only happens when compiling to  Flash 7 (Flash 7
support is planned for LPS 3, but is not yet supported in the current
release).  It seems to be dependent on timing ... are you running your
app with debugging enabled (debug=true in the query args) ? If not,
try running with debugging, and see if that changes the behavior one
way or the other (either always works , or always fails)
