Harakiri commented on DISPL-152:
--------------------------------
Well, afaik this issue still hasnt be resolved even after 18 month =/
its very important to get to know which excerpt of a list Displaytag is
currently showing
however - i made a workaround its not pretty bug it works
within the <display:column> tag i add the object into a session variable
i.e. lets say i render a list of users my objects name is User
i do
<display:column property="name">
ArrayList currentlyDisplayedUsers =
session.getAttribute("currentlyDisplayedUsers");
currentlyDisplayedUsers.add(user);
session.setAttribute("currentlyDisplayedUsers",currentlyDisplayedUsers);
</display:column>
after a submit or whatever i just retrieve this value and do know which entries
were displayed
because displaytag executes only code within the column tags for the CURRENT
rendered entries
> document how to access the currently displayed sub-list/excerpt

> my struts application hands over a list to displaytag such as a mail inbox.
> Displaytag then shows an excerpt of that list.
> When I want to perform an action on this sub-list, I don't see a way how to
> access it (I am NOT using javascript in the browser!).
> I guess, having a a start and an end range number would be sufficient.
> If this can be done, please document it!
> If not, I guess it would be great if displaytag would store an Integer for
> the beginning of the range as
> "DISPLAYTAG_RANGE_START" attribute into my javax.servlet.http.HttpSession and
> a "DISPLAYTAG_RANGE_END" Integer as well. This way, my subsequent struts
> actions could work on the currently visible part of the list (e.g. deleting
> those 30 mails from my inbox!)
> What do you think?
