FlexibleMapAccessor.java throws NPE under certain conditions
------------------------------------------------------------

                 Key: OFBIZ-1898
                 URL: https://issues.apache.org/jira/browse/OFBIZ-1898
             Project: OFBiz
          Issue Type: Bug
          Components: framework
            Reporter: Adrian Crum


If you use a statement like

<set field="listItem" from-field="someMap.someList[0]"/>

and someMap doesn't exist, FlexibleMapAccessor.java throws a NPE at line 148.

I tried some ideas to fix it, but they all broke the class. I don't know enough about it to fix it.

David E. Jones commented on OFBIZ-1898:
---------------------------------------

Did you try adding something like this just before that line (148):

                if (newBase == null) {
                    return null;
                }

It would treat it the same way it treats a missing list.

On a side note, what sorts of issues did you run into with other changes you made?
