My comment is about the html:cancel tag. The documentation for its property attribute has an explicit warning, it ends with "You will need to do your own cancel detection.". I would like some hints to alternative "cancel detection" implementations, for example when you are using LookupDispatchAction.
At the moment, some documentation pages (like http://struts.apache.org/userGuide/struts-html.html ) contain 'future' information, e.g., the checkbox tag has an attribute 'errorStyle' which is not valid in the current release version of stuts. It says "Since: Struts 1.2.5" but I would have found it helpful if there were some indication that this is not yet the current version.
Missing Some Attributes in Documentation for html:form
There is no mention of the "name" and "type" attributes. Seems like these used to be listed in the documentation, and I'm currently using both attributes with struts-html-el.
The 'name', 'type' and 'scope' attributes were deprecated on 7 August 2002 and removed on 10 August 2003.
