Subject [jira] [Commented] (JEXL-144) Empty array property setting fails
Date Sat, 02 Nov 2013 04:54:17 GMT

    [ https://issues.apache.org/jira/browse/JEXL-144?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13811873#comment-13811873
] 

Woonsan Ko commented on JEXL-144:
---------------------------------

The error seems to happen because it tries to resolve the type of the first array item in
order to find the best setter method.
However, if an empty array is provided, it cannot detect the component type of the array,
and so it fails to find a proper method from the object array (Object[]) argument.

> Suppose a bean has an array property setter method (e.g, public void setStrarr(String
[]) ).
> If I use an expression like this with an empty array, then it fails with the error message,
"inaccessible or unknown property strarr".
>   // example expression
>   bean.strarr = [ ];
