Support for Java 5 - Generics in Tapestry 4.0.2
Hi,
I've been having fun writing a page in Tapestry, but I could see a lot of duplication about, so I introduced generics, with various objects that get injected by hivemind also extending generic objects.... big mistake.
The problem is... I am now getting errors to the effect of "method doesnt exist methodName(path.to.BaseGenericClass);"... This is a little concerning as I don't really want to have lots of duplication everywhere unless I absolutely have to.
Is this a known problem with Tapestry 4.0 that is fixed in 4.1?
Thanks
Gareth
