I think Jelly is so flexible that there's half a dozen ways to do so.
• I thought the Ant way of doing was supported (where addConfigured and
add and... may work) but I am unsure.
• some tags use findAncestorWithClass which I don't like since it breaks
if within a defined script
• I would suggest a fancy one which I think is the best style since it
allows defined scripts to be used but requires a current snapshot of
jelly: make jemos:filter tags be classes and use
XMLOutput.objectData(object) at the end in their doTag classes.
- If not within a jemos:clanker tag, that would result into the
toString() of object to be output as text.
- in the doTag of jemos:clanker, however, you have cared for an
XMLOutput which catches the objectData calls of class filter-data... and
you use them.
Hope that helps.

Ah ok...Thanks :)
Then I have a question ;)
I have got a tag (let's say <jemos:clanker> which launches an analysis
process. I want to pass some 'filters' to the analysis process, so I
am thinking of doing something like:
<jemos:clanker attr...>
<jemos:filter type="process" processJavadocs="true"
processAnnotations="true" />
<jemos:filter type="javadocs" tags="@clanker1, @clanker2, etc." />
<jemos:filter type="annotations" name="@ClankerDoSomething"
level="class" />
<etc...>
</jemos:clanker>
<jemos:clanker> and <jemos:filter> map to a TagSupport class. I'd like
that each <jemos:filter> to be added to
<jemos:clanker> in a programmatic way. I thought: ok, from within
<jemos:clanker> body I can obtain a reference to all the
<jemos:filter> filters and retrieve their values. Is this the right
thing to do? If so, is the getBody() method the right place where to
do that?
Many thanks for any answers.
Marco

Hey Marco,
newbies are welcome at Jelly... and I fear the assistance of the list
is needed since documentation can be somehow... lagging behind.

Hi, I've got a class which extends TagSupport. This class has got
many initialization attributes. Some of them are Collections, some
are arrays. How to I pass, from within the Jelly tag, all the
values to a collection or to an array?
Why does it not work to pass have a setter be called by the
collection with such a thing as
<j:new var="coll" className="java.util.ArrayList"/>
<j:mute>${coll.add('a')} ${col.add('b')} ${col.add('c')}</j:mute>
<t:tag collection="${coll}"/>
?
Or do you want to type in a litteral collection (such as
['a','b','c']) ?
