Summary: ClassCastException when using fox:widow-content-limit
Product: Fop
Version: 1.0dev
Platform: PC
OS/Version: Windows Vista
Status: NEW
Severity: normal
Priority: P2
Component: page-master/layout
AssignedTo: fop-dev@xmlgraphics.apache.org
ReportedBy: matthias8...@gmx.at
I created a table with the fox:widow-content-limit attribute. If a table cell
contains a list-block element, which has the space-after attribute, a
ClassCastException occurs.
A small testcase is attached.
