We installed AEM Forms 6.2 CFP4.
Our submit has ns2 on the xml. Any idea why? Seems to be something to do with panels.
XSD has no mention of "ns2".
<?xml version="1.0" encoding="UTF-8"?>
Appears to be with JDK jdk1.8.0_92 (my machine). Doesn't occur with jdk1.8.0_74 (another machine).
But we doubt the JDK is related.
Also doesn't seem to occur on my machine when I don't do a prefill.
What kind of Form are you using? Is it XFA,XSD or None based Form Model?
Let me get back to you on that.
