Ate Douma created SCXML-272:
-------------------------------
Summary: Javascript engine (Nashorn) doesn't support native XML
DOM operations
Key: SCXML-272
URL: https://issues.apache.org/jira/browse/SCXML-272
Project: Commons SCXML
Issue Type: Improvement
Affects Versions: 2.0
Reporter: Ate Douma
While the Groovy and Jexl datamodels, being 'native' Java engine, can be used
for XML DOM operations with <assign> and evaluation expressions, this doesn't
work with the Nashorn Javascript egnine.
There simply is no Javascript DOM operation support in Nashorn, and there also
doesn't seem to be an (practical) extension or something available elsewhere.
As a consequence, Commons SCXML cannot fully implement the SCXML mandatory
features for the ecma datamodel.
This also is the cause of failure for 2 out of the last 3 non-passing [W3C
SCXML IRP|https://www.w3.org/Voice/2013/scxml-irp/] tests (186 tests total):
# [test557|https://www.w3.org/Voice/2013/scxml-irp/557/test557.txml]
# [test561|https://www.w3.org/Voice/2013/scxml-irp/561/test561.txml]
both testing a similar expression like:
{code:java}cond="var1.getElementsByTagName('book')[0].getAttribute('title') ==
'title1'"{code}
which simply fails to execute in Nashorn Javascript.
Both the Jexl and Groovy datamodels have no problem evaluating the above.
Note that ecma datamodel support itself is optionally, but *if* it is supported
*then* mandatory tests like the above should pass.
As finding a practical solution or fix for this seems unlikely, I'm just
reporting this here, but will close as Won't Fix (can't reallly).
