ClassCastException when absolute positioning a table css #162

Open GoogleCodeExporter opened 9 years ago

Found an interesting error today.

Given the following input:

<html>
<head>
  <title>HELLO</title>
  <style type="text/css">
  #test {position:absolute; right:70px;}  
</style>
</head>
<body>
<table>
<tr>
<th>hello</th>
<td id='test'>hello</td>
</tr>
</table>
</body>
</html>

The render fails with this exception:

org.xhtmlrenderer.render.AnonymousBlockBox cannot be cast to 
org.xhtmlrenderer.newtable.TableCellBox
java.lang.ClassCastException: org.xhtmlrenderer.render.AnonymousBlockBox cannot 
be cast to org.xhtmlrenderer.newtable.TableCellBox

If I remove the absolute positioning, it renders fine.  Is this a bug or 
expected behaviour given that absolute positioning a table cell is rather 
strange (but what one of our users wants to do!).

I am also facing the similar issue. If I remove position: absolute;, it renders 
fine. Is there anyway to fix this issue ?

This issue is still present in 9.0.4. I just tested the given example and it 
raised the following exception:
