After checking several times I think theres a problem in WAAnchorTag
>> #goto and not my code:
Yep, this is certainly a bug. I will have a look at it.
Avi recently made some enhancements in the handling of URLs and
anchors, I will load the latest Seaside and pray that we have URL
objects instead of strings in WAAnchorTag now, so the #goto: should
be much easier ;-)
