I am also interested in this. The IterateTag uses "lengthCount" to keep
track of the current iteration, however this is a protected variable and
there is no getter to expose it.
Would it be possible to put in a public getLengthCount() in the IterateTag?
This wouldn't solve Chris's problem directly but then other tags embedded in
the IterateTag could then use:
findAncestorWithClass(this, IterateTag.class)
to get hold of it and then call getLengthCount().
I have two different scenarios where I needed to do this and I've
sub-classed IterateTag to achieve it. However it would be really useful if
it was in the original version.
I have a <html:row oddColor=".." evenColor=".."> tag which generates rows
with alternating colors which needs this and from various posts I've seen
might be useful to quite a few people. It generates <tr
bgcolor="..">....</tr> elements.
