Re: History tokens and vertical menu panel

Anything before the hash "#" needs to be identical from place to
place otherwise you'll be loading the page from the web server and
losing state. There are ways to get around this (i.e. servlet
session state , cookies, preservation of state as url params...)
however if your intention is to not go back to the web server for a
new page then you'll have to make sure your that your url is the same
before the hash.
In addition, using "a href=" will still cause page reloading on some
versions of internet explorer
Try using
1) A Gwt Anchor with your own event handler to inovke "
History.newItem(token );"
2) InlineHyperlink with targetHistoryToken="token value"
Hope this helps,
David
