Woonsan Ko updated JEXL-144:
----------------------------
Attachment: jexl3-empty-array-patch-3.txt
jexl2-empty-array-patch-3.txt
Hi Henri,
Thanks a lot for the review and remark!
I'm attaching a revised patch for 2.0 branch (jexl2-empty-array-patch-3.txt)
and another for trunk (jexl3-empty-array-patch-3.txt) which don't have
'isEmptyArrayValue' member any more.
Regarding "another way (from the JEXL3/Uberspect)", yes, that looks a lot
better to add this kind of code in Uberspect.java maybe instead of
PropertySetExecutor even though I don't fully understand the design changes in
JEXL3 yet. I'll try to understand JEXL3 Uberspect and try a patch in that way
soon. (So, you can disregard the patch for trunk now.)
By the way, I'm going to use JEXL2 in our document processing engine module
(which is based on SCXML 2.0) in the short term. So, we're definitely
interested in having this feature in JEXL2, not JEXL3 in the short term.
In the longer term, I'll probably want to upgrade it to JEXL3 because it might
be more flexible/customizable and stable.
Best,
Woonsan

> 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
