Hi Craig,
can you try to check and build htmlunit from its SVN repository and use
it with WebTest. If I correctly remember some issues with table length
have been fixed since release 1.9. This may already solve your problem.

A JavaScript error occurs when the combination of table.deleteRow() and
table.insertRow() is used. The deleteRow statement is nested in a while loop
where "table.rows.length > 0" controls the looping. The insertRow statement
must have at least 2 rows to insert in order to see the exception. And
finally, this will only occur on the 2nd call (onclick events used below) from
the page. The first call succeeds.
This scenario makes me think that a variable (an index is what the JavaScript
exception mentions briefly below) is not being properly reset.
The HTML and webtest script are below.
If possible could someone try to reproduce this? If it's a real bug, then let
me know where to open it.
Thanks,
Craig
