Re: [Htmlunit-user] TypeError

[David D. K. <ddk...@ki...>]

Try to create a reduced test case that fails, then post a bug.  Line =20
530 from the attached menu.js file doesn't look like it matches up =20
with the error message below, though:

     snObj =3D document.getElementById('submenu-'+mid);

Looking at the source for =20
com.gargoylesoft.htmlunit.javascript.host.Style, I would say that =20
access to attributes is possible, although I've never used this =20
feature myself.
