Nullsafe method selection?
--------------------------
Key: OGNL-46
URL: https://issues.apache.org/jira/browse/OGNL-46
Project: Commons OGNL
Issue Type: Bug
Reporter: Christian Grobmeier
Priority: Minor
For some reason it seems that with Struts 2.3.1 sending a null value does lead
to confusion in OGNL. For example:
setToken(String token){}
should be set by OGNL. It works, if String != null. If String is null, OGNL
claims this method does not exist for unknown reason. Probably this is somehow
related to Struts, but feeling says solution can be found in OGNL.
Workaround is not to send null ;-)
