Subject: RE: [displaytag-user] List contains only a subset or limited reco
rds
Hi Friends,
I have just started using the displaytags and found it really really
interesting. The pagination and sort features are simply superb. I have one
observation with this tag library. I am developing a struts based web
application and I would like to have the column header to show the locale
specific titles and not the hard-coded strings. I mean to say, that display
tags should support i18n (internationalization). When I say i18n, struts
tags support i18n.So I prefer using the struts resource bundle instead of
writing a different one altogether.
Solution: I tried extending the display tag library as follows so as to
support i18n.
1) A new interface named ResourceProvider is added that has one method
"String getMessage()"
2) I have implemented this interface and named it
StrutsResourceProvider.This resource provider picks up the keys from the
struts resource bundle. If somebody likes to use a different resource
bundle, then just simply implement ResourceProvider interface.
3) The table tag is changed to have a new attribute named
resourceProvider.This attribute expects the fully qualified name of the
class that implements ResourceProvider (eg:-
com.myCompany.StrutsResourceProvider)
4) Now in the column tag, I have added one attribute named resource.The
possible values for this are true|false.
How it works ?
Lets say that the resourceProvider is set properly on the table
tag.Now if the "resource" attribute of the column tag is true, then the text
that we give for the "title" is considered as the resource key.If the
"resource" is false, then the text for the "title" is taken as is.This way
we are allowing the user to give hardcoded strings as titles if need be.
Please let me know if you have any better ideas in this regard. For any
further help, mail me back.I shall help you out.
Regards
Kiran Kumar

This is interesting because I just started working on
the search section of my site and I know I'm going to
run into this issue soon.
The more I think about the 'empty object' approach, I
don't see why it won't work - for navigation.
However, you'll run into issues sorting columns and I
suppose it might make sense for scrollable results to
just turn sorting off. Can still leverage all the html generation which
would still be good.
Anyway, interesting idea, thx.
