> ArrayList Iterator Cursor set to Object Aray in OGNL
> ----------------------------------------------------
>
> Key: OGNL-260
> URL: https://issues.apache.org/jira/browse/OGNL-260
> Project: Commons OGNL
> Issue Type: Bug
> Reporter: Julian Ryan
> Priority: Major
>
> When running the following example in the latest (3.2.11):
> {code:java}
> import ognl.MemberAccess;
> import ognl.Ognl;
> import java.lang.reflect.Member;
> import java.util.Map;
> public class OgnlTest {
> public static void main(String ... args) {
> // Lazy allow everything for this test
> Map ognlContext = Ognl.createDefaultContext(null, new MemberAccess() {
> @Override
> public Object setup(Map context, Object target, Member member,
> String propertyName) {
> return null;
> }
> @Override
> public void restore(Map context, Object target, Member member,
> String propertyName, Object state) {
> }
> @Override
> public boolean isAccessible(Map context, Object target, Member
> member, String propertyName) {
> return true;
> }
> });
> try {
> Object o = Ognl.getValue("#editsIter =
> @java.util.Arrays@asList(\"one,two,three\".split(\",\")),
> #editsIter.iterator()", ognlContext, new Object());
> ognlContext.put("iterator", o);
> Object o2 = Ognl.getValue("#iterator.next()", ognlContext, new
> Object());
> System.err.println(o2);
> } catch (Exception e) {
> e.printStackTrace();
> }
> }
> }
> {code}
> The iterator cursor is set to an Object array with a single value containing
> the array values of the ArrayList instead of the values in the ArrayList.
> This causes calling iterator.next() to just returns the whole set of
> ArrayList values.
> The expected behavior would be similar to the following snippet:
> {code:java}
> import java.util.Arrays;
> import java.util.Iterator;
> public class IteratorTesting {
> public static void main(String ... args) {
> Iterator iterator =
> Arrays.asList("one,two,three".split(",")).iterator();
> while(iterator.hasNext()) {
> Object o = iterator.next();
> System.err.println(o);
> }
> }
> }
> {code}
> In short, for version 3.2.11 the iterator.next() returns an Object[] of
> length 1 and in version 2.6.7 calling iterator.next() works the same as the
> second snippet.
