Use the TagData.getAttribute("name") method to get the name of the variable
to create. Remember that it can't be marked <rtexprvalue> in the web.xml
file or it won't have a value at translation time.

Hi Chris,
Thanks for the pointer. I am a bit confused though with the following:
I would like to implement the second suggestion you made, ie to allow the
variable to be named explicitly from within the tag. My problem is that
in the IterationTagExtraInfo I must create a variable with a name, if the
name of the variable is itself variable, how do I pass this name to the
the IterationTagExtraInfo class? If you know what I mean? Do I just
create a getVariableName in the IterationTag and then call it from the
IterationTagExtraInfo class?
I tried changing the scope of the variable which doesn't really work as
then I get the
"Bean 'name' already defined" error when the tags are not nested. I tried
changing the 'declare'
boolean parameter to false, so the tag will update the variable, rather
than creating a new one but since the variable doesn't yet exist when
first calling the tag, this didn't work either.
??
Thanks for the help
Joel
