RE: [htmltmpl-java] testing for parameter existence

[Costantino, D. <Dan...@gs...>]

Philip,

Thanks for getting back to me.  I did a little more testing and realized my
try {} .. catch {} wrapper really doesn't solve the problem.  It turns out
that getParam() will throw a NoSuchElementException exception on a valid
parameter if the parameter's value has not yet been set.  I'll stop short of
calling that a bug, but I think it's a serious problem.  Is that the
intended behaviour?

Dan

Currently this seems to be the only way, but I think it is reasonable 
enough to add another method that will do what you want.  Expect it in 
the next version, or get CVS in a few hours.
