RE: LinkTag

[Howard Moore <Ho...@Datapulse.com>]

Another problem with including in-page links using something like 

<html:link href="/some/page.html#bottom"/>

as you suggest is that you can't set parameters using the 'name' or
'paramXXX' attributes because it would produce something like;

<a href="/some/page.html#bottom?param=value"> 

not 

<a href="/some/page.html?param=value#bottom">

exception: IncompatibleClassChangeError?

[Katarina Nelson <ka...@appium.com>]

Hi,
I´m changing my struts tags from the old lib (struts.tld) to those three
news (html, logic & bean) and get this strange exception. Do somebody knows
what I do wrong?
Thanks,
Katarina
