Lukasz Lenart updated WW-4025:
------------------------------
Description:
In the latest code, lukaszlenart refactored some code. Using a recent build, I
get the following error (relevant code follows).
{noformat}
java.lang.NullPointerException

{noformat}
The relevant source code is:
{code}
+ ParsedValueEvaluator ognlEval = new ParsedValueEvaluator() {
+ public Object evaluate(String parsedValue) {
+ Object o = stack.findValue(parsedValue, asType);
+ if (evaluator != null) {
+ o = evaluator.evaluate(o.toString());
}
+ return o;
}
- }
{code}
Appears as if there is an assumption that the stack.findValue() will always
return a non-null value.
