Thanks for your advice. I really just wanted
to prevent having to duplicate hard coded form bean
names, i.e. in my jsps and in the config.xml.
I wrote a tag to get it from the action mapping,
but alas, that didn't work either. For one, my
action mapping was null(probably some misconfig on
my part). Secondly, it looks like when you
nest a custom tag within the attribute of another
custom tag, it doesn't get evaluated, so
doing <logic: iterate name="<mylib:getFormBeanName />" ... />
won't work anyway. Although this works fine for html tags.
thanks,
dan
