In BIRT 2.1.2
param["param_name"] == null would work
In BIRT 2.2 this does not work and has to be changed to
param["param_name"] .value == null

Is this going to be fixed in 2.2.1?

I think that's not a bug, in BIRT2.2 if you want to know whether params's
value is null, you should use the params["xxx"].value, just like if you
want get the displayText you should use the params["xxx"].displayText.
Another words, if you create a parameter, the parameter's object has
exsited, so the parameter will never be null, but his value could be null.
That's not a compatibility issue I think.

Regards!
