Thanks Adam
Implemented it and it worked.
One quick question, when we use these tags, one of the options get selected
by default. How can we modify the tag so that NONE of the options get selected
by default ?
Thanks.

Let's say your TestBean class has getFoo() and getBar() methods both
which return Collection objects. If these objects are instances of
LabelValueBean objects it's really easy, if they are not, I'd recommend
converting them to these bean objects either in your bean class or in
the action (though the latter could add additional overhead if not done
correctly). Assume also that your TestBean class has getter and setter
methods for ONE Foo and ONE Bar (say getOneFoo(), setOneFoo(String foo),
getOneBar(), setOneBar(String bar).
In your Action's execute method (or a method called by execute(...))
type (assume testBean is an instance of the TestBean class and the
getFoo() and getBar() methods return Collections of LabelValueBean objects):
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
...
Collection fooCollection = testBean.getFoo();
Collection barCollection = testBean.getBar();
request.setAttribute("fooCollection", fooCollection); //
"fooCollection" can be any text you want - i recommend using a final
static reference instead of a hard-coded string.
request.setAttribute("barCollection", barCollection); // same
comment applies
...
}
in your JSP, you would say:
your collection on the request -->
property="value"
labelProperty="label"/>
and,
property="value"
labelProperty="label"/>
to render list boxes of your model data.
html:options knows that you have a Collection of objects (in this case
LabelValueBean objects) that have the methods getValue() and
getLabel(). Note that since these attributes are configurable, you can
make the Collection a collection of any type of bean you want so long as
all the beans in the collection have a getXXX() methods where XXX are
the values of the attributes "property" and "labelProperty".
When your form is submitted, the setOneFoo(String) and setOneBar(String)
methods will be called and set with the value of the "property"
attribute. the "labelProperty" attribute dictates what is actually
displayed to the user in the browser.
Let me know if you have any more questions.
