Nice writeup Joel and good to have for a quick reference.
Thomas, I know your question was about JSP functions, but I just
wanted to mention that for the actual example you mentioned, you
can probably get Stripes to do the work for you.
Something along the lines of:
<stripes:select multiple="multiple"
name="item.scoringCategories">
<stripes:options-collection
collection="${actionBean.someProperty}"
value="id" label="name"/>
</stripes:select>
If item.scoringCategories does not contain the values to render
as selected, you can also use the value= attribute of
<stripes:select>.
Cheers,
Freddy
