Hi,

HttpUnit, which is acting as the browser behind the scenes of
jWebUnit, does not yet support access to the getElementById method on
the HTMLDocument class.  While that may be supported soon, your method
subsequently updates a table cell attribute, which also isn't activity
supported by HttpUnit, and is less likely to be supported anytime
soon.

Essentially, using any HttpUnit based tool with applications relying
extensively on  javascript manipulation of elements is problematic. 
HttpUnitOptions class (even when HttpUnit is used behind jWebUnit)
will allow you to supress javascript exceptions and test other aspects
of the page, but if the javascript is being used to accomplish core
functionality which must be tested, you may do better with a tool that
drives a browser instance.

The HttpUnit site's homepage has a link to a javascript support page,
which spells out which properties / methods on DOM objects are
currently supported.

Jim
