Rob,
Thanks for the quick reply and the palette sample.
I think i m avoiding using palette cuz i cant fig out an easy way to convert
my java.util.List of composite objects (or watever u call em...the ones with
objects inside objects) to a IPropertySelectionModel.
I'll take a look at tassel. good ref! thx
i m curious though to learn more about the select component with
multiple=true. So if the select component displayed a collection of objects,
what would be a way (in the form listener) to get hold of the selected
objects?
as i mentioned b4, i iterate through all the colln objects for isSelected()
to be true, but looks like setSelected() is not turning the flag to
true...or maybe i m missing something?
thanks again!

Try the select multiple component in tassel?
Otherwise, the contrib:palette works well, too.
Using it is really about the same as using PropertySelection.
The only difference is that you're passing a (modifiable) list instead
of a single object in.
Here's an example...
<select jwcid="@contrib:Palette" model="ognl:coursesModel"
selected="ognl:selectedCourses"
availableTitleBlock="ognl:components.unenrolled"
selectedTitleBlock="ognl:components.enrolled"/>
<span jwcid="[EMAIL PROTECTED]">
Unenrolled
</span>
<span jwcid="[EMAIL PROTECTED]">
Enrolled
</span>
