I am trying to pattern match on a primitive array such as String[] or
SomeObject[]. The documentation only mentions collections in the section
about From.
Would a pattern match syntax such as...
rule "My rule"
when
$source : SourceObject()
$myObject : MyObject() from $source.returnsAnArrayProperty
then
....
..be correct? If not, how can capture and loop over every object in an
array (not Collection)?
I have tried the above and I get a ClassCastException.

No...no one?
My primary concern is to apply a filtering pattern to an array like so...
(this array is non collections based)
when
$source : SourceObject()
$filtered : MyObjectType( field == "criteria" ) from
$source.getMyObjectTypes() << returns MyObjectType[]
then
... do something with the filtered object
I am getting a ClassCaseException in the from line.
Anyone? Please?

OK...new discovery...the class case exception only happens if I apply a
criteria to the pattern:
For example:
$filtered : MyObjectType() from $source.getMyObjectTypes() << returns
MyObjectType[]
works while...
$filtered : MyObjectType( field != null ) from $source.getMyObjectTypes() << returns
MyObjectType[]
Gives me a ClassCastException.

Henry,
Can you plz open a JIRA with a test case. It looks like a bug to me.

I have recorded this issue with a test case in JIRA:
JIRA ID : JBRULES-1446
Would love to see this resolved since I am constantly hitting up against
it...our code uses tons of arrays.
