Well, It doesn't iterate (end method), what means "When there aren't any
objects left to iterate over it does some cleanup and
goes away." ???????

Thats my problem.

Well, the answer is I am developing a tag that uses the S2 tag library for
make this, for example:

		<jsongl:jsonarray name="array3" items="%{maquinas}" var="item">
			<jsongl:jsonproperty value="%{codigo}"/>

This would create a json object valueStack that hold the json array object
name "array3" this json object is create using the value stack of S2, in
this way I can create any json object using the object that are into the
valueStack context (and also can use the ognl).

the code generate is below:

<script type="text/javascript">
valueStack = {
array3 = ["m1", "m2"]

In this way I can access from javascript to any object in JSON way ;) that I
configure to using this tag, so
there is not limit to develop a component that use a LOT javascript and at
same time access to objects into the valueStack, with this the develop is
more simple (less code of S2 custom develop of component is needed).
