Bug in ParameterParser?
In a push screen class I have the following code:
ParameterParser pp = data.getParameters();
NumberKey topicid = pp.getNumberKey("topicid");
My problem is that when the topicid parameter
is not present I get a NullPointerException on the
second line of code above rather than topicid
being set to null.
Here is some output from turbine.log:
[Sat Jun 30 00:17:19 GMT+10:00 2001] -- ERROR -- Turbine.handleException: null

Can someone confirm whether or not this is a bug.

This seems to have been fixed already. You need to use a more recent version
of BaseValueParser.java.
I just also fixed the same bug in getStringKey().
