Where is the documentation for Struts tags
Where is the latest documentation for using Struts 2 tags? I had a
problem
earlier in the week trying to use the optiontransferselect tag which I
still
haven't been able to get working. Earlier today, I started trying to get
the
checkboxlist tag to work with a map and I'm still failing
miserably.
In both cases I get the infamous
tag 'checkboxlist', field 'list', name 'roles': The requested list key
'availableroles' could not be resolved as a
collection/array/map/enumeration/iterator type. Example: people or
people.{name}
tag 'checkboxlist', field 'list', name 'roles': The requested list key
'availableroles' could not be resolved as a
collection/array/map/enumeration/iterator type. Example: people or
people.{name} - [unknown location]
style of error message when I fire up my action. Googling suggest that
from
the number of recent posts on StackOverflow and Java Ranch for example,
I'm
not the only one frustrated with this. When the struts tag reference page
for checkboxlist gives as its only example "" and neither pages give any indication on how these tags
interact with the action code, I begin to feel that this is all starting
to
be more trouble than it's worth.
Someone, somewhere must know of a url where this is all explained with
crystal clarity with useful code examples - I just can't find it at the
moment.
Yours in desperation

Re: struts session help
Hello:
You can use session context if implements SessionAware for example:
public class MyAction extends ActionSupport implements SessionAware {
private Map session;
public String execute() {
session.put("categoryList", EComplaintType.values())
return SUCCESS;
}
public void setSession(Map session) {
this.session = session;
}
}
SALUDOS!!

Re: struts session help
Hi,
you could put/get from session like so:
ActionContext.getContext().getSession();
You can define a "parent" action (implementing preparable) with a
prepare() method that retrieves data and store it in session for later
(and check each time if data is already in session) and puts it into
properties with public getters that your other actions extending that
one (and jsps) will inherit.
