What I meant whas that you could have put whatever variable name in the che=
ck, it always returns null, even if the variable is not threre at all. Sorr=
y if I formulated that wrongly.
=C2=A0
So the current behaviour is:
=C2=A0
|| *Case* || *Java* || *EL* ||
| var exists and has a non-null value | value | value |
| var exists and has value of 'null' | null | fails |
| var does not exists | null | fails |
=C2=A0
This should at be identical I think, at least for the case where the variab=
le exists. I created a little patch that solves this (all unit tests still =
are green). If you file a jira issue about this, I'll attach the patch to i=
t that make EL return null if the variable exists but has a value of null. =
It does make the last case identical (not it should, and if it should, shou=
d it fail? or should EL also return null?) Ask that in the Jira issue to.
