           Summary: NullPointerException on
SVGStylableElement.getStyle()
                    method
           Product: Batik
           Version: 2.0
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: CSS
        AssignedTo: batik-devxmlgraphics.apache.org
        ReportedBy: flaviostutzgmail.com


I am getting NPE errors when calling getStyle() for
SVGStylableElements.
If I wait for the GVTTreeBuilder to complete, it doesn't
raise the error at the
first load of a file in JSVGCanvas, but subsequent loads
raises the error.

I found that NPE is raised because the variable 'cssEngine'
in
AbstractStylableDocument is null at the moment of the call,
but I may wait for a
long time and it is still null (except for the first time I
load the file in
JSVGCanvas).

I don't have experience in Batik development. What do I have
to wait for to be
garanteed that all style stuff is built?

Fragment that raises the NPE:
result = ((SVGStylableElement)elem).getStyle();
