-------------------------------
Component/s: (was: layout/unqualified)
layout/inline
> NPE in InlineStackingLayoutManager when hyphenate without break opportunity
> ---------------------------------------------------------------------------
>
> Key: FOP-1615
> URL: https://issues.apache.org/jira/browse/FOP-1615
> Project: Fop
> Issue Type: Bug
> Components: layout/inline
> Affects Versions: 0.95
> Environment: Operating System: Linux
> Platform: PC
> Reporter: Carsten Metzler
> Priority: Blocker
> Attachments: mantis779.fo, module.fo.gz

> 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;
> }
