Summary: Re-parenting an element with a SET element causes
NullPointerExceptions
Product: Batik
Version: 1.7
Platform: Other
OS/Version: other
Status: NEW
Severity: normal
Priority: P2
Component: GVT
AssignedTo: batik-dev@xmlgraphics.apache.org
ReportedBy: frodef@stud.cs.uit.no
In order to move an element to the "top", I use the following script, which
removes an element from its parent, and inserts it as the last child of the root
element (thereby ensuring it gets draw last).
function raise(e) {
if
(document.documentElement.childNodes.item(document.documentElement.childNodes.length-1)
!= e) {
e.parentNode.removeChild(e);
document.documentElement.appendChild(e);
}
However, if the element in question has a SET sub-element, something in the
event processing gets confused, and each subsequent event causes a
NullPointerException like this:

The following SVG demonstrates the effect: click the rectangle to trigger the
raise function, and then observe the exceptions:
