#370 rows[index].cells.length always returns zero
Trying to access row/cell in a table by index fails
Pls find the ReadMe.txt inside demo.zip to run the
sample script.
Problem Statement
Created a table with 3 rows. While trying to access
each row by index, the junit test case
fails. Have uploaded the demo.zip file to demonstrate
the problem which contains the
index.html with javascript and a junit test case
(DemoTest.java) to run the same. Place all
the necessary jar files listed in Readme.txt in lib
folder for the test case to run. Also
have attached the Readme.txt to run the TestCase.

Seems to be a string conversion problem.
The test can be simplified with:
<html>
<head>
<script>
function getContent()
{
var table = document.getElementById('data');
alert("Row 0:" + table.rows[0]);
}
</script>
</head>
<body onload="getContent()">
</body>
</html>
What should give [object HtmlTableRowElement] for FF and
something like [object] for IE. htmlunit doesn't respect
currently string conversion like browsers do (is it
important for you?) but I agree that it shouldn't cause an
expection.

Now fixed in SVN.
row cell length always return zero now..Have attached the index.html
rows[index].cells.length always returns zero

Please add a comment when you reopen an issue!
I've checked again and the current SVN state of htmlunit
behaves the same than FF for the 2 index.html attached to
this issue.
