> In the org.apache.fop.layoutmgr.inline.InlineStackingLayoutManager an 
> NullPointerException is thrown in the "applyChanges"-method, when the 
> variables prevLM AND currLM both are null.
> line 333-338: 
>             currLM = (InlineLevelLayoutManager) oldElement.getLayoutManager();
>             // initialize prevLM
>             if (prevLM == null) {
>                 prevLM = currLM;
>             }
> The getLayoutManager-method of the ListElement-class returns null when no 
> position is set, so currLM is null. If prevLM is null, too, prevLM is set to 
> currLM - so both are null. In the following code the applyChanges-method is 
> called on prevLM without null-check.
> As workaround I inserted the following code after line 338:
>             if(prevLM == null && currLM == null) {
>               continue;
>             }
