Well,
The problem is that I populate the value from the Java side, using an
accessor method.
Also, I get the following message even before selectedCompleterResponse has
a value:
Async Error: Jess reported an error in routine get
while executing (get ?r keyCode)
while executing (eq "ASP" (get ?r keyCode))
while executing rule LHS (TEQ)
while executing rule LHS (TEQ)
while executing rule LHS (TECT).
Message: No such property: keyCode.
What happens in that case if selectedCompleterResponse is null (I was
assuming it would not try to go further)?
