[T5] Gotcha when working with Groovy and T5
Just thought that might interest some people.
I stumbled over a bug in Groovy's handling of annotations while translating
some components from Java. It is known and already filed here:
http://jira.codehaus.org/browse/GROOVY-3278
You can't use static constant variables in annotations, so
@Parameter(defaultBinding = BindingConstants.LITERAL)
won't work for example, while
@Parameter(defaultBinding = "literal")
will.
This is quite a bit of a putoff, since if you start a bigger application now
you might run into problems when upgrading Tapestry at some time in the
future and also it might affect your own component parameters when you work
with enums or constants. It's not fixed yet in 1.6.1-SNAPSHOT but hopefully
it gets worked on soon.

Well, the intent of those constants is not to shield against a change
(we aren't going to rename "literal" to "fixed" or something), but to
help the compiler catch typos that would otherwise be discoverred at
runtime.
