There seems to be a bug with ExtensionFunctions and collections as
parameters.
Example:
List list = new ArrayList();
list.add("foo");
list.add("bar");
context.getVariables().declareVariable("myList", list); Collection
values = context.getValue("test:getItems($myList)");
* Values returns: [bar, bar] not [foo, bar]
Extension Function:
public static Collection getItems(Collection items) {
return items;
}
It seems that the iterator building the collection is always returning
the last element. Since the existing unit test
(ExtensionFunctionTest.testCollectionMethodCall) is only testing the
size, the test passes. I added a test to check the actual values passed
to the extension function.
