The reason
<nested:nest property="submission">
<nested:iterate property="attributes">
..
works is because the <nested> tags keep track of the context in which they are in;
i.e. the call to the 'attributes' property by <nested:iterate> is made relative to the
parent bean which is 'submission'.
For your custom tag to pick up on this, you will have to mimic this functionality.
Take a look at the source for the nested framework; maybe it's a simple matter to use
this feaure in custom tags (such as yours) without having to re-invent the wheel.

Subject: How should I pass an exposed bean variable as custom tag parameter?
Arg, i can't see how to pass bean variables as parameters to my own custom tag. It
seems like this should be easy, but it appears to be a common problem, previous posts
have led to my attempting various methods . . . without success, perhaps since i'm
trying to pass an array.
Please help!
I'm trying to pass a variable, exposed by the <nested> tag, to a custom tag.
'Submission' is the bean, and 'attributes' is a Object[] in 'Submission', to
demonstrate, this prints from the array:
<nested:nest property="submission">
<nested:write property="ID"/>
<nested:iterate property="attributes">
<nested:write property="name" />
<nested:write property="value"/>
</nested:iterate>
</nested:nest>
What I'd like to do is pass submission.attributes into my tag as the variable data . .
. I've tried many ways, this is the "phonetic" code, which doesn't work.
<nested:nest property="submission">
<app:showAttributes data="attributes"/>
</nested:nest>
thanks in advance,
Loren
