links not active with preceeding blocks that use a padding

           Summary: links not active with preceeding blocks that use a
                    padding
           Product: Fop
           Version: 0.20.4
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: pdf renderer
        AssignedTo: fop-dev@xml.apache.org
        ReportedBy: wendler@five-towers.de


Hi there,

the activatable area of an internal/external link seems to get computed such 
that the 'y' coordinate leaves out paddings of preceeding blocks. That has the 
effect that one can activate the link only when targeting a bit HIGHER on the 
page. If one moves the mouse cursor over the link text it simply doesn't seem 
to work (no cursor change, no effect when clicking)

... below is a complete sample demonstrating the bug.

WORKAROUND: use 'space-...' instead of 'padding...'

Best regards, Mike.

           FOP is the world's first print formatter driven by XSL formatting
           objects. It is a Java 1.1 application that reads a formatting object
           tree and then turns it into a PDF document. The formatting object
           tree, can be in the form of an XML document (output by an XSLT engine
           like XT or Xalan) or can be passed in memory as a DOM Document or (in
           the case of XT) SAX events.
